As a child, I was horrified by people who wrote in books. In high school, I’d go through my textbooks at the start of the new school year and carefully erase the penciled scribbles and doodles left by previous students. Once I started college I was expected to write in books, to annotate books, to know how and what to annotate. At the time, I rejected the very thought of annotating books; it just felt wrong. I wasn’t going to to do it.
I successfully avoided annotating books until my senior year as an undergraduate English major, when I first took my first Chaucer class in Middle English. The Robinson Chaucer, while an admirable scholarly text, was not student friendly. There were no notes on the page; they were all appendices at the back of the book. I resorted to making careful glosses using a fine point orange-body Bic Pen (my favorite tool for annotating books for decades).
As I read more texts in Middle and Old English and Celtic languages in graduate school, I used marginal notes to help me find particular passages, and glossed difficult words and concepts that weren’t otherwise explained by the text. Once I started teaching, I glossed with colored pencils in order to make finding a particular passage or note easier while lecturing and leading discussions. I still regularly annotate books, and thought I might save others some time by explaining how and why I annotate.
What Does it Mean to Annotate
Here’s a formal dictionary definition of annotate from the American Heritage Dictionary:
v.tr.To furnish (a literary work) with critical commentary or explanatory notes; gloss.
v.intr.To gloss a text (s. v. American Heritage Dictionary annotate).
- The act or process of furnishing critical commentary or explanatory notes.
- A critical or explanatory note; a commentary (American Heritage Dictionary, s.v. annotation).
In other words, when we annotate a book or text, we mark it up, via marginal notes or glosses, marks in the text itself, or highlighting and underlining passages in order to create additional meaning and understanding for ourselves. By careful annotation, we make a text our own. Careful, thoughtful annotation helps us engage with the text and remember it.
Annotating books (or other reading matter) helps us read as an active, engaged reader more likely to remember what you read. When we annotate or mark texts to emphasize the important information, the goal is to emphasize the key points or concepts. Don’t simply highlight or underline everything. Prioritize the material that you know you will use later in your own work, or that you want to be able to find quickly and easily later.
Glossing and Marginal Notes
Glossing, or making notes in the margins and within the text itself can help enormously when you locate something you read and need to remember. Glossing can be either a note that summarizes or comments on a passage or it can be a label, for instance, adding the word distinction in the margin, to note when an author draws a distinction between two items, or analogy, when an author compares an unfamiliar concept to a familiar one. Or you might gloss something with short note to provide a definition of an unfamiliar term. This last method was the most common kind of gloss in earlier eras when scribes would annotate a foreign term with a marginal note, as in the image to the right from the 8th century Gospels of Lindisfarne. A monk named Aldred added Old English glosses between the lines of the Latin text of the Gosples as a translation aide. Medieval and earlier glosses like this eventually resulted in the modern glossary, a collection of terms appended to a book). Etymologically Modern English gloss derives from Middle English glose, from Old French, from Medieval Latin glōsa, from Latin glōssa, foreign word requiring explanation, from Greek, “tongue, language” (American Heritage Dictionary s.v. gloss 2).
Highlighting and Underlining
Highlighting, that is using a colored marker or pencil that colors text so that the text is still readable through the color, is a useful technique for annotating books. It is different from underlining in that the entire line(s) of text are colored in highlighting, whereas underlining usually means to draw a thin line under the line of text.
Don’t get carried away with underlining or highlighting. If you highlight or underline more than about 15% of a given page, you’re probably not prioritizing the information. Only highlight those concepts or points that are most important.
As an alternative to underlining or highlighting, consider annotating by drawing a vertical line in the margin to mark the passage in question, possibly with a note in the margin about why it’s important.
Annotation Styles and Codes
It’s a good idea to create your own personal style of annotating books. You might circle important concepts, and underline terms and definitions. Consider using the margin to summarize key points with a brief note. It can also be useful to use the margin to ask questions that are answered in that section of the text. Many readers use a question mark in the margin to make it easy to find a section or concept that they do not understand. It’s helpful to create your own personal style of annotating. You might circle important concepts, underline terms and definitions, or summarize key points with a brief note in the margin. You can see an example of one way of annotating a text here.
In some cases, you might want to have a short note on the flyleaf of a book, if you’ve used special annotation symbols just for that book.
Keep It Clean
Many readers particularly students planning to resell their textbooks hate the idea of annotating books. Sometimes it’s just a personal dislike; sometimes it’s because the book in question isn’t yours, so you shouldn’t mark it permanently. In that case, consider using post-its that you can remove before selling the books or keep in books you own. There are special stickynotes designed explicitly for making notes about a page as you read. Alternatively, I often take notes by hand in a notebook or pad of paper or on my computer as I read instead of or in addition to marking up the book.
If you routinely use .pdfs or ebooks, there are digital equivalents for the forms of annotation used in printed books. There are minor differences in the methods for accessing and creating the annotations based on the app in question, but the basic methodology is similar. Typically you can make digital marginal sticky notes, dog-ear pages or book mark them with a note, highlight text, and underline. With most .pdf readers, you can also draw circles, arrows, and other shapes, on the .pdf pages.
Annotating has two primary purposes; it allows us to find particular passages or ideas in a text, and it aids our memory and understanding because as we closely read and think about the text, and engage with it by annotations, we make the text our own. We add personal meaning and interpretation.
Tools for Annotation
You don’t actually need fancy tools to annotate books or documents. But the right tool can make a difference in legibility and utility.
Smaller sticky notes, the familiar 1 3/8 inch x 1 7/8 inch notes are useful for making marginal notes without marking the page. Page flags make it easy to find the pages and passages you know will be important without writing in your books. Transparent stickie niotes let you see the text you are responding to.
Sometimes it’s helpful to take extensive notes about a page without writing on the page. These removable notes have tabs that you can label, making it easy to find the specific topic you’re looking for. And you can use them to take notes while you read and then remove them, either to save in a notebook for later use or discard when you no longer need them. There are a lot of different kinds of sticky notes, with all sorts of uses. It’s often convenient to have a portable assortment to use not only for annotating, but for note-taking, and marking sections for review.
Taking notes while you read, either in the book or text itself or on paper is often particularly useful when you’re researching for use in something you write later. Cornell notes, which have a central area for the note, a margin for comments or page references, and a summary field at the bottom for questions or ideas to emphasize can be particularly helpful in annotating and taking notes about what you are reading. You easily print your own; there are many free templates to print your own online, or you can use paper you already have, and draw some lines with a straight edge. I did this for years, and eventually made my own template.
A multi-pen with red, blue, and black ink, and a .05 mm mechanical pencil is exceedingly useful as an all-purpose writing and annotating tool. You can use it to make color-coded annotations, take notes, and you have erasable pencil too.
The utility of highlighting passages with very visible color is that they’re easy to find. But sometimes it’s better or easier to use pencil to make notes and marks that you can erase later. These Apsara pencils are smooth-writing dark graphite wood-case pencils and they come with a sharpener and an eraser. You will be surprised how nice these are to write with, and by the quality of the sharpener.
