How to Build a Digital Commonplace Book from Paper Books
A simple system for keeping the passages you underline without turning reading into administration.

Start with a reason to keep the line
A commonplace book is a personal collection of ideas, passages, observations, and questions. Its value does not come from collecting everything. It comes from keeping the things you expect to revisit.
When a sentence earns an underline, pause long enough to ask why. It may explain an idea clearly, challenge an assumption, or give language to something you already felt. That short reason is often more useful than a complicated tagging system.
Use one dependable capture ritual
Finish the page before reaching for your phone. Then photograph the marked passage, review the extracted text, and correct anything that the camera or extraction missed. Keep the book title and page number with the quote whenever possible.
The review matters. A searchable transcription is useful only when it still says what the author wrote. Treat extraction as a first draft and let your own eyes make the final decision.
Return to the collection
A commonplace book becomes valuable through reuse. Search it while writing, revisit a few saved passages at the end of each week, or choose one idea to discuss with somebody else.
BookQuotes supports this paper-to-library workflow: add the book by ISBN, capture marked pages, review the result, and keep the passage in a searchable local library.
