Quick answer
For reference books, start with the task you need most: reading, searching, marking, or listening. Set up only the tools that support that task.
Reference books are opened repeatedly for specific facts rather than always read front to back.
Choose the file mode first
Use reflowable text for flexible books when possible. Keep fixed pages for PDFs, slides, diagrams, or documents where layout matters.
Fast search, contents, and bookmarks matter more than linear progress.
Make navigation fast
Use search for terms, contents for sections, bookmarks for chosen return points, and saved progress for normal continuation.
Keep notes short
Write the reason a passage matters instead of copying the whole passage.
This makes review faster later.
End with a clear return point
Before closing, leave a bookmark or trust saved progress.
A reading system works better when the next session starts in seconds.
If the first fix does not work
Try another known-good reference books example. If the second one works, the first file or item is probably the problem. If both fail in the same way, the app, phone, or setting is more likely.
