A unified catalog can describe every book in your reading life. Unified file access is a separate question: ownership, format, account access, and lending restrictions determine where each book can actually be opened.
Make a source map
Write down every source before importing anything. Include store accounts, loose files, old drives, bundle downloads, and library loans. Add one field for how you access the book and another for whether you own or borrow it.
Keep records and files distinct
A catalog entry can point to a library loan without becoming a permanent copy of that loan. Similarly, a store purchase may belong in your inventory even when its protected file cannot be opened by another reader.
Use a small common vocabulary
Choose simple statuses: unread, reading, finished, reference, and paused. Use source names as metadata rather than creating a separate reading system for every store. One search should reveal where a book is and how to open it.
The details, at a glance.
| Consider | What to look for |
|---|---|
| DRM-free EPUB | Catalog and import the file into a compatible reader |
| Protected store purchase | Catalog it; verify authorized reading options |
| Library loan | Record the loan, due date, and access location |
| Bundle download | Preserve the original and choose a reading format |
A few things worth asking.
Can one app open every purchase?
Do not assume so. Store protection and reader support can limit access even when every title fits in one catalog.
Should borrowed books be in my inventory?
Yes, if they are clearly labeled as loans and include their due date or lending source.
