The Lost Art of Marginalia: Why Humans Have Always Written in the Margins

Last updated: August 2026 | A guide to marginalia, reading notes, commonplace books, notebooks, annotation, personal thinking, and Dingbats* notebooks

Before notes apps, highlights, screenshots, saved posts, and digital bookmarks, people had margins.

The side of a page was not empty space.
It was a place to argue.
To agree.
To underline.
To remember.
To ask questions.
To leave evidence of a thought in the exact place it appeared.

This is marginalia: the notes, marks, symbols, comments, reactions, and fragments written in the margins of books and documents. For centuries, readers wrote beside the text they were reading. They copied passages into commonplace books. They kept notebooks beside books. They used blank spaces to respond to ideas, save useful lines, track arguments, and leave behind traces of how they thought.

Today, we often think of writing in a book as damage. But historically, marginalia tells a different story. It shows that reading was never meant to be passive. The margin was where the reader became part of the page. And maybe that is why the habit still matters. Because whether we write in a book, keep a reading notebook, build a commonplace book, or carry a journal, we are still doing something very old: giving our thoughts a place to meet the words that shaped them.

At Dingbats*, we believe paper is not only for finished ideas. It is for thoughts while they are happening. A notebook can become a modern margin: a place for reading notes, reflections, questions, quotes, lists, reactions, sketches, and fragments that might otherwise disappear.

The margin was never really empty. It was waiting for a response.

Quick Overview: What Is Marginalia?

Term	Meaning
Marginalia	Notes, symbols, comments, marks, or drawings made in the margins of a book or document
Annotation	The act of marking or commenting on a text
Commonplace book	A notebook used to collect quotes, ideas, passages, observations, and useful knowledge
Reading notebook	A notebook used to record thoughts, reactions, quotes, and reflections from reading
Modern margin	Any physical place where thoughts are captured beside or after reading
Dingbats* fit	Wildlife for personal notes, Earth for organized reading systems, Pro for visual thinking and creative responses

Marginalia is not just writing in the margins. It is evidence that a person was thinking with the page.

What Is Marginalia?

Marginalia refers to the marks people make in the margins of books, manuscripts, printed pages, and documents. It can be as simple as a line beside a sentence. Or it can be a full conversation with the text. A reader might write:

“I agree.”
“Why?”
“Important.”
“Use this later.”
“Wrong.”
“Beautiful.”
“Remember this.”
“This reminds me of…”
A date.
A name.
A symbol.
A question.
A reaction they could not leave unrecorded.

Marginalia can be neat or messy, serious or funny, private or meant for someone else to find. Some marginal notes are scholarly. Some are emotional. Some are practical. Some are nothing more than proof that a sentence mattered enough to stop the reader.

Common Types of Marginalia

Type	Example
Reaction	“I love this” or “I disagree”
Question	“What does this mean?”
Summary	A short note explaining the paragraph
Cross-reference	“See page 42” or “This connects to…”
Personal memory	“This reminds me of my grandfather”
Symbol	Star, arrow, underline, bracket, exclamation mark
Correction	Fixing an error or adding missing context
Argument	Responding directly to the author
Creative spark	A line that becomes an idea for something else

Marginalia is where reading becomes active. The reader is no longer just receiving the text. They are answering it.

Why Humans Have Always Written Beside What They Read

Humans write in margins because thinking rarely happens in a straight line.

A book gives you the author’s words. The margin gives you your own. When something makes us pause, we want to keep the pause. When a sentence feels important, we want to mark it. When an idea connects to something else, we want to capture the connection before it disappears. That impulse is ancient.

People have always needed somewhere to put the thought that arrives while reading, listening, studying, learning, or observing. Sometimes that place was a book margin. Sometimes it was a notebook. Sometimes it was a commonplace book. Sometimes it was a letter, diary, field note, sketchbook, or loose piece of paper.

The form changes. The instinct stays the same.

Why Marginalia Exists

Human Need	How Marginalia Helps
To remember	Marks the parts worth returning to
To understand	Turns reading into active processing
To argue	Gives the reader space to respond
To connect	Links one idea to another
To preserve	Keeps a thought from disappearing
To personalize	Makes the text part of the reader’s life
To create	Turns reading into the beginning of new writing

Marginalia is not only about books. It is about the human need to leave a trace of thought.

The Margin as a Conversation

A margin can feel like a conversation across time. The author writes. The reader responds. A future reader sees both.

This is one of the most interesting things about marginalia. A marked-up book does not only contain the printed text. It contains layers of attention. Someone’s questions. Someone’s frustration. Someone’s admiration. Someone’s correction. Someone’s memory. A clean copy shows the text. An annotated copy shows a relationship with the text.

What Marginalia Can Reveal

Marginal Note	What It Shows
Underlining	What felt important
Questions	What confused or challenged the reader
Exclamation marks	What surprised them
Corrections	What they knew or believed
Dates	When the reading happened
Personal references	How the text connected to life
Cross-references	How ideas linked together
Long notes	Where reading became thinking

This is why old marginalia can feel intimate. You are not only seeing what someone read. You are seeing where their mind stopped.

Marginalia and the History of Thinking on Paper

Marginalia belongs to a much larger history of thinking on paper. People have long used notebooks, diaries, commonplace books, manuscripts, letters, and reading notes to collect ideas. These were not always polished forms of writing. They were working spaces.

A diary might record daily life. A notebook might hold fragments. A commonplace book might collect quotes and useful passages. A margin might capture an immediate response. Together, these forms show that writing has always been a way of processing the world.

Different Forms of Thinking on Paper

Form	Purpose
Marginalia	Respond directly beside the text
Commonplace book	Collect quotes, passages, and useful knowledge
Diary	Record daily life and personal experience
Notebook	Capture ideas, drafts, lists, and observations
Field notes	Record what is seen in the world
Letter	Think through a message to another person
Sketchbook	Process ideas visually

A notebook is not separate from this history. It is one of its most flexible forms.

What Is a Commonplace Book?

A commonplace book is a notebook used to collect knowledge. Historically, people copied passages, quotes, observations, facts, poems, arguments, and ideas into a notebook so they could return to them later. A commonplace book was not a diary exactly, and it was not a planner. It was more like a personal library of useful thoughts.

Today, a commonplace book can include:

• quotes from books
• lines from articles
• ideas from conversations
• words you want to remember
• references for future projects
• questions you keep returning to
• personal observations
• lists, fragments, and notes

It is one of the closest relatives of marginalia because both habits come from the same impulse: do not let a good thought vanish.

Marginalia vs Commonplace Book

Marginalia	Commonplace Book
Written directly in the book or document	Written in a separate notebook
Responds to a specific page	Collects ideas from many places
Often immediate and spontaneous	Often more organized or curated
Stays attached to the original text	Becomes part of a personal knowledge system
Good for direct annotation	Good for long-term memory and reuse

A margin captures the thought where it happens. A commonplace book gives that thought a place to live.

Why We Stopped Writing in the Margins

Many people no longer write in the margins of books.

Sometimes because the book is borrowed.
Sometimes because it feels too precious.
Sometimes because resale value matters.
Sometimes because we read digitally.
Sometimes because school taught us to keep books clean.
Sometimes because we think a finished page should stay untouched.

There are good reasons to avoid writing in certain books, especially library books, rare books, borrowed books, or editions you want to preserve. But when we stopped writing in margins, we also lost something useful: the habit of responding physically to what we read. The solution is not necessarily to mark every book. The solution is to create a new margin. That margin can be a Dingbats* Notebook.

Why a Notebook Makes a Good Modern Margin

Reason	Why It Helps
Keeps books clean	Good for borrowed, rare, or special books
Holds notes from many sources	Books, podcasts, films, conversations, articles
Gives more space	No tiny margin limits
Supports organization	Add headings, dates, indexes, and sections
Encourages reflection	Notes can expand beyond a quick reaction
Becomes searchable by memory	You remember where you wrote it
Turns reading into a record	Your thoughts collect over time

A notebook lets you keep the spirit of marginalia without needing to write directly inside every book.

The Notebook as a Modern Margin

Your Dingbats* Notebook can become a margin for your whole life. Not just for books. 

For articles. Meetings. Conversations. Ideas. Trips. Projects. Films. Dreams. Plans. Questions. Moments.

Anything that makes you pause deserves a margin. That is what a notebook gives you: space beside life.

Modern Marginalia Can Look Like

Source	Notebook Response
Book	Quote, reaction, question, theme
Podcast	One idea worth keeping
Film	Scene, line, feeling, visual note
Meeting	Key decision, action, thought
Conversation	Phrase, memory, follow-up
Travel	Observation, sketch, ticket, route
Work project	Lesson, idea, direction
Personal life	Reflection, list, small detail

A margin is not only the side of a printed page. It is any space where your mind answers the world.

Why Marginalia Makes Reading More Active

Reading can be passive. You move through the words. You understand them. You finish the chapter. Then a week later, most of it is gone. Marginalia changes that.

When you mark a sentence, write a question, copy a quote, or summarize an argument in your own words, you slow down. You are not only reading. You are processing.

That makes the reading more personal and more memorable.

How Marginalia Improves Reading

Habit	What It Does
Underlining	Identifies what matters
Writing questions	Reveals what you do not yet understand
Summarizing	Turns someone else’s words into your own understanding
Copying quotes	Preserves language worth returning to
Making connections	Links ideas across books and experiences
Writing reactions	Shows how your thinking changed
Dating notes	Gives context to your response

You do not need to annotate everything. In fact, you should not. The best marginalia is selective. It shows where your attention became sharper.

What to Write in the Margins

Good marginalia does not need to be complicated. It can be practical, emotional, critical, creative, or personal. The best notes are the ones that help you return to the idea later and understand why it mattered.

Marginalia Prompts

Prompt	Example
What is the main idea here?	“The author is arguing that memory needs physical anchors.”
What do I agree with?	“Yes — this explains why handwritten notes feel different.”
What do I disagree with?	“Too simple. This ignores habit and context.”
What does this remind me of?	“Similar to the meeting we had about product storytelling.”
What should I use this for?	“Blog idea / email intro / campaign angle.”
What question does this raise?	“Is nostalgia always useful?”
What line is worth keeping?	Copy the sentence into your notebook
What does this make me feel?	“Strangely comforting.”

A margin does not need a full paragraph. Sometimes one word is enough.

Symbols for Marginalia and Reading Notes

Symbols are useful because they make annotation faster. You can use them in a book margin, in a notebook, or in a reading journal.

Simple Annotation Symbols

Symbol	Meaning
★	Important
?	Question
!	Surprising
→	Connects to another idea
✕	Disagree
✓	Agree
“ ”	Quote worth copying
⏳	Remember for later
💡	Idea sparked
📌	Use in a project

You can create your own system. The point is not to make the page look clever. The point is to make your thinking easier to find.

How to Start a Marginalia Notebook

A marginalia notebook is a notebook you keep beside what you read, watch, hear, or notice. It can be simple. You do not need a complicated setup. You only need a few repeatable sections. The Dingbats* Wildlife Collection is perfect here!

Simple Marginalia Notebook Setup

Section	What to Include
Source	Book, article, podcast, film, conversation, meeting
Date	When the note was made
Quote or idea	The line, phrase, or concept that caught your attention
Your response	What you thought, felt, questioned, or connected
Use later	How you might return to it
Page or reference	Where to find the original again

A page might look like this:

Source: Book title / article / podcast
Date: August 27, 2026
Idea: “The margin is where the reader becomes visible.”
My response: This could become a blog introduction. It makes reading feel active, not decorative.
Use later: Content idea / product storytelling / newsletter line

That is enough. The value comes from returning to it.

Marginalia Notebook Page Ideas

A marginalia notebook does not need to be only about books. It can become a living archive of what your mind reacts to.

Page Ideas

Page Idea	What to Include
Reading reactions	Notes from books, essays, articles, and poems
Quote bank	Lines worth keeping
Question page	Questions you keep returning to
Argument page	Ideas you disagree with and why
Connection map	How one idea links to another
Vocabulary page	Words that feel useful or beautiful
Project sparks	Ideas that might become work later
Conversation notes	Things people said that stayed with you
Film or podcast notes	Lines, themes, references, reactions
“Use this later” page	Ideas for writing, work, art, or planning

The margin can be intellectual. But it can also be deeply personal.

Marginalia for Readers

For readers, marginalia is a way to make books part of your thinking life. It helps you remember what you read, but more importantly, it helps you remember who you were when you read it.

The same book can mean something different at different times. A note written at 19 may feel different when you read it at 29. A line you underlined during a difficult week may mean something else years later.

That is the beauty of reading notes. They preserve the conversation between the book and that version of you. This is where the Dingbats* Reading Journal comes in handy!

Reading Note Ideas

Page Type	What to Write
Favorite lines	Quotes you want to keep
Character notes	People, motives, relationships
Theme page	Ideas that repeat throughout the book
Personal response	What the book made you remember
Disagreement page	Where you pushed back
Book-to-life connection	How the book connects to your own experience
Final impression	What stayed after finishing
Rereading notes	How your response changed later

A good reading notebook does not only summarize the book. It records your relationship with it.

Marginalia for Work and Ideas

Marginalia is not only for literature. It is useful for work, strategy, creative thinking, and problem-solving. Every project has its own margins: side notes, questions, rough ideas, rejected directions, small observations, and thoughts that do not fit neatly into the final document. A notebook gives those thoughts a place to go.

Work Marginalia Ideas

Situation	What to Write
Meeting	Questions, reactions, decisions, follow-ups
Campaign	Lines, angles, audience insights, rejected ideas
Product development	Observations, feature notes, user comments
Research	Quotes, facts, sources, questions
Design review	What works, what feels off, what to test
Brainstorming	Half-ideas before they become plans
Feedback	Comments you want to revisit
Post-launch	Lessons, results, future improvements

The most useful work ideas often begin as side notes. A margin keeps them from getting lost.

Marginalia for Creative People

Creative work often begins in the margins.

A line beside a sentence.
A sketch beside a meeting note.
A question beside a reference.
A phrase copied down quickly.
A color combination.
A half-formed title.
A visual idea that does not belong anywhere yet.

A creative notebook is a margin for unfinished things. That matters because finished work depends on unfinished notes.

Creative Marginalia Ideas

Creative Use	Notebook Response
Moodboard	Collect colors, textures, phrases, references
Sketch	Draw the visual idea before it disappears
Title bank	Save possible names and headings
Line bank	Collect phrases that might become copy or poetry
Visual notes	Combine words, arrows, layouts, and symbols
Draft fragments	Save the beginning of an idea
Material tests	Swatches, pens, paper, textures
Inspiration log	Where the idea came from

The Dingbats* Pro Collection is especially suited to this kind of creative marginalia because its 160gsm mixed media paper supports sketches, brush pens, markers, visual notes, moodboards, and light washes. Some thoughts do not arrive as sentences. They arrive as shapes.

Marginalia for Everyday Life

Life has margins too.

The few minutes before a meeting.
The back of a receipt.
The corner of a page.
The note you write while waiting.
The thought that comes during a walk.
The phrase someone says in passing.

Not everything needs a full journal entry. Some things only need to be caught.

Everyday Marginalia Ideas

Moment	What to Capture
During a walk	What you noticed
After a conversation	A phrase or feeling
While traveling	A detail, route, ticket, or memory
During a meal	A place, dish, or person
At work	A small lesson or idea
Before sleep	A thought that keeps returning
While reading	A line that connects to life
At the end of the week	What mattered more than expected

A notebook is useful because life rarely gives you clean categories. It gives you fragments.

Which Dingbats* Notebook Works Best for Marginalia?

Different kinds of marginalia need different kinds of notebooks.

Some people want a simple everyday notebook. Some want structure. Some want creative space. Some want a reading companion. Some want a place for quotes, notes, sketches, and scraps.

Dingbats* has different collections for different ways of thinking on paper.

Dingbats* Notebook Guide for Marginalia

Collection	Best For
Wildlife Collection	Personal reading notes, everyday thoughts, letters, reflections, travel notes
Earth Collection	Organized reading systems, indexes, collections, trackers, structured notes
Pro Collection	Visual notes, sketches, creative responses, moodboards, mixed media pages
Reading Journal	Reading logs, reviews, quotes, book notes, structured reading reflections

The best notebook is not necessarily the most formal one. It is the one that matches how your thoughts naturally appear.

The Wildlife Collection as a Personal Margin

The Dingbats* Wildlife Collection works well as a personal marginalia notebook because it feels expressive, portable, and suitable for everyday writing.

Animal covers give the notebook character. The 100gsm cream paper supports longhand notes, reflections, quotes, lists, and daily thoughts. Practical features such as bookmarks, pockets, elastic closures, and pen loops across relevant formats make it easier to keep the notebook close.

Use Wildlife For

Use	Why It Works
Book notes	A personal place for quotes and reactions
Daily observations	Easy to carry and return to
Travel marginalia	Capture thoughts beside movement and place
Letters and drafts	Personal writing feels at home
Conversation notes	Save phrases, memories, and ideas
Reflection	Cream paper gives a warm writing experience

Wildlife is the notebook for thoughts that feel personal. The ones that belong to your life as much as your reading.

The Earth Collection as an Organized Margin

The Dingbats* Earth Collection works well for people who want their marginalia to become a system.

It is useful for readers, planners, researchers, and thinkers who like indexes, numbered pages, collections, and structured layouts.

Instead of letting notes scatter, Earth helps organize them.

Use Earth For

Use	Why It Works
Quote index	Find important lines later
Reading collections	Organize books, themes, and notes
Research notes	Keep sources and thoughts together
Idea tracking	Follow concepts across time
Habit and reading trackers	Connect reading with routine
Project notes	Turn side thoughts into action

Earth turns marginalia into a personal knowledge system. It is the notebook for people who want their side notes to become searchable.

The Pro Collection as a Visual Margin

The Dingbats* Pro Collection works best when your marginalia is not only written.

Some ideas need images, color, arrows, diagrams, lettering, swatches, and visual structure. Pro gives those ideas more room because of its larger B5 format and 160gsm mixed media paper.

Use Pro For

Use	Why It Works
Visual reading notes	Combine quotes, symbols, sketches, and diagrams
Moodboards	Build visual responses to books, projects, or ideas
Creative research	Collect references, textures, and fragments
Sketch notes	Turn thoughts into images
Calligraphy and lettering	Make words visual
Mixed media responses	Add light washes, collage, and layered pages

Pro is the margin for visual thinkers. The people who need more than lines.

How to Build a Reading Notes System

A reading notes system should be simple enough that you keep using it. You do not need to write pages of analysis after every chapter. You only need a repeatable way to capture what mattered.

Simple Reading Notes System

Step	What to Do
1. Write the source	Title, author, date started
2. Copy key lines	Only the ones that truly matter
3. Add your response	Why did this line stop you?
4. Create a symbol system	Star, question mark, arrow, exclamation mark
5. Add page references	So you can find the original
6. Summarize after finishing	What stayed with you?
7. Index important ideas	Build a map of recurring themes

This creates a notebook that is more useful than a list of books read. It becomes a record of what those books did to your thinking.

How to Annotate Without Ruining a Book

Not every book should be marked. Library books, borrowed books, rare books, special editions, and books you want to keep clean should stay unmarked. But you can still annotate around them.

Clean Annotation Alternatives

Method	How It Works
Notebook notes	Write quotes, page numbers, and reactions separately
Sticky notes	Mark temporary thoughts without writing on the page
Index cards	Keep one card per chapter or idea
Reading log	Summarize thoughts after each session
Quote bank	Copy lines into a notebook
Symbol key	Use removable tabs or marks
Chapter pages	Give each chapter its own notebook section

A notebook lets you keep the thought without changing the book. That is the modern compromise.

Marginalia Prompts for Your Notebook

When you do not know what to write, use a prompt. The best prompts help you move from passive reading to active thinking.

Reading Marginalia Prompts

Prompt	Use It For
What is the strongest sentence on this page?	Finding what matters
What do I agree with?	Clarifying your position
What do I disagree with?	Building your own argument
What does this remind me of?	Connecting text to life
What question does this raise?	Keeping curiosity active
What would I tell someone about this?	Summarizing simply
Where could I use this idea?	Turning reading into action
What changed in my thinking?	Tracking growth
What would I ask the author?	Creating dialogue
What do I want to remember in one year?	Saving lasting value

The goal is not to produce perfect notes. The goal is to leave yourself something worth returning to.

Marginalia and Memory

Writing in the margins is partly about memory. A mark says: this mattered. But a notebook goes further. It says: this mattered enough to keep.

Memory is not only about storing information. It is about creating meaning. When you copy a quote, write a reaction, or summarize a passage, you are choosing what belongs in your mental archive.

How Marginalia Helps Memory

Action	Memory Benefit
Underlining	Identifies importance
Copying	Slows down attention
Summarizing	Improves understanding
Questioning	Creates active engagement
Connecting	Links new ideas to old ones
Reviewing	Makes thoughts easier to return to
Indexing	Helps ideas become findable

A thought written down has a better chance of becoming part of you.

Marginalia and Personal Style

Marginalia is also a form of personal style. Not in the fashion sense. In the thinking sense.

The way you mark a page reveals how you read. Some people underline. Some write long notes. Some draw arrows. Some use symbols. Some copy quotes. Some write emotional reactions. Some build systems. Some keep things messy.

Your marginalia does not have to look like anyone else’s.

Different Marginalia Styles

Style	What It Looks Like
Minimal	Stars, lines, page numbers
Academic	Summaries, arguments, questions
Emotional	Personal reactions and memories
Creative	Sketches, symbols, layouts
Practical	Ideas to use later
Collector	Quotes, vocabulary, references
Reflective	Connections to life and experience

A notebook gives your style room to develop. Over time, your notes become recognizable as yours.

Why the Most Interesting Notes Are Often Unfinished

Margins are full of unfinished thoughts. That is part of their charm.

A question without an answer.
A sentence that trails off.
A phrase circled three times.
A note that only makes sense to the person who wrote it.
A connection that might become useful later.

Not every note needs to become something. Some notes are valuable because they capture thinking while it is still alive.

Why Unfinished Notes Matter

Unfinished Note	Why It Has Value
Half idea	Could become a project later
Question	Keeps curiosity open
Fragment	Preserves a feeling or insight
Sketch	Captures visual thinking quickly
Crossed-out line	Shows the thought process
Messy page	Records reality, not performance

The notebook is not only for finished thoughts. It is for thinking in progress.
