Quick answer
Organize a large ebook library by separating what you are reading now from long-term storage. Use clear names and avoid duplicate copies.
A large ebook library can include hundreds of books with different reading states.
Use three simple groups
A small structure is easier to maintain.
- Reading now
- Want to read
- Finished or archive
Name files clearly
Use “Author - Title” for books and “Topic - Date” for documents when that helps.
Keep the same title in one main place so notes and progress stay attached to the same copy.
Use progress instead of extra folders
Let reading progress show which books are active.
Use folders or collections for broad groups, not every possible category.
Back up important files
Your reader library is not a backup by itself.
Keep another copy of files you cannot easily replace and test that the backup opens.
