A sketchbook can contain finished drawings, quick experiments, written notes, and pages you want to revisit. An index helps you find those useful parts without reorganizing the book or removing pages. Keep the system small enough that it does not interrupt the act of drawing.
Choose a location method
Use existing page numbers or add simple numbers where appropriate. If numbering every page feels burdensome, identify important spreads with a removable marker suitable for the paper. Avoid attachments that could damage delicate work.
Index only what you want to retrieve
A page does not need an entry merely because it exists. Record a study that answered a question, a technique you want to repeat, or an unfinished idea worth revisiting. Leave ordinary practice pages unindexed if you have no reason to search for them.
An entry might read: “Pages 18–19: mug proportion studies; compare handle placement.” That is more useful than “drawings” and shorter than a full account of the session.
Use a few consistent search terms
Choose subjects or techniques that match how you look for work: portraits, buildings, color tests, or composition ideas. You can give one page more than one term when useful. Avoid making a complex category tree before you know what the book contains.
Separate a study from an action
A useful reference page is not automatically a task. If you want to develop an idea, write a specific next step in your planning notes and point back to the sketchbook location. Keep “interesting” distinct from “committed project.”
For example: “Try the window composition on a larger sheet” is an action. “Window study, page 26” is a reference. Preserving the distinction prevents every rough idea from becoming an obligation.
Add context that affects reuse
Record materials, reference source, or conditions when they matter to your interpretation. If you plan to share or publish work derived from a reference, check the relevant permissions separately rather than assuming an index note settles that question.
Review at a natural pause
Add entries after a session or when a book is nearly full. On the cover or first page, identify the date range and where the index is located. If the index is digital, include enough information to identify the physical book.
Use the short practice plan when an indexed study suggests a focused next exercise.
