📝 About this app

Free and ad-free, My Library allows you to store your personal library and to perform a quick search within it.

My Library allows you to:
- Add a book to your library by scanning its barcode (title, author, cover, summary, published date, publisher, ...)
- Add a book to your library via its ISBN number or by keyword
- Add a book to your library manually
- Look for a book in your library
- Sort your library by titles, names, categories, read / unread, ...
- Export your library within an Excel file
- Import a library from a previously exported library
- Manage your wishlist
- Display some statistics

For intellectual property reasons, real book covers are not allowed on Google Play screenshots. But in the app, you will of course be free to add official covers for your books.

Please note that My Library uses many services (like Google Books, Amazon, etc.) in order to match ISBN numbers and the books you are looking for, therefore if an ISBN number is not found, it is because it is not referenced within those services.
