Annotating and tabbing a book

Annotation turns reading into a record, and tabbing turns that record into something you can find again a year later. The two habits are usually described together and are separate skills: one is about what you write, the other about how you retrieve it.

Deciding what the marks are for

The first decision is the purpose, because it determines everything else. Marking to remember a passage, marking to argue with the book, marking to trace a pattern across a series and marking to find quotable lines for a group discussion all produce different systems. A reader who has not chosen produces a book covered in marks with no way to use them.

A small, stable system

Systems fail by growing. Five colours is already more than most readers can apply consistently across four hundred pages, and a system that is applied inconsistently is worse than none, because the marks stop meaning anything. Three categories is a workable maximum: something like one for craft, one for plot mechanics and one for lines worth returning to.

Whatever the categories, write the key on the inside cover on the first day. A system remembered rather than recorded will have drifted by the middle of the book, and reconciling the two halves afterwards is tedious.

Marks that survive

Pencil is reversible and does not bleed through thin paper. Fineliners are crisper and permanent. Highlighters are fast and, on the lighter paper used for long paperbacks, frequently show through to the other side, which is worth testing on the copyright page before starting.

Tabs come in two useful sizes. Narrow ones mark a line and can be written on. Wider ones mark a chapter or a section and are better used sparingly, since a book with fifty tabs is not indexed, it is fringed.

Marginal notes

The most valuable notes are the ones written for a future reader who has forgotten the context. A note that reads simply that a passage is good is unusable six months later. A note that says what the passage does, or what it contradicts fifty pages earlier, is a working index entry. Page-number cross references in the margin are the single highest-return habit for anyone reading a long series.

Doing it digitally

Ebook highlighting solves retrieval completely, since every mark is exportable and searchable, and loses the spatial memory that makes physical annotation easy to navigate. A reasonable compromise is to highlight digitally and keep a short running note of chapter numbers, which restores enough structure to find things quickly.

Permission to leave it alone

Annotation is a working method, not a requirement. It suits rereading, close attention and group discussion. For a book being read once, at speed, for pleasure, it is friction with no payoff, and there is nothing to be gained by adding it.
