How to Import a Calibre Library into All My Books

Calibre is excellent at what it was built for: converting formats, sending books to a Kindle, and keeping ebook files in one library folder. A lot of people then try to stretch it into a home library catalog — paper books, loans, ISBN on the spine, a shelf you can browse — and that is where it starts to fight you.

All My Books 6.1 reads a Calibre library directly. You do not retype titles. You do not copy the EPUB/PDF tree into a new folder. The catalog is an index on top of the files Calibre already has.

Calibre vs All My Books: different jobs

Keep both if you convert formats. Switch the day-to-day catalog to All My Books if you also own paper books, lend copies, or do not want another program renaming files on disk.

Task	Calibre	All My Books
Ebook file library + conversion (EPUB ↔ MOBI, send to device)	What it is for	Not a converter. Opens the file in the reader Windows already uses
Copies / renames files into its own library folder	Yes — that is the Calibre library	No. Files stay where they are
Printed books, ISBN, barcode / webcam scan	Not the focus	Title, ISBN, barcode scanner, webcam ISBN in 6.1
Loans, shelf location, reading log	Custom columns if you build them	Built-in loan manager and location field
Audiobooks in the same catalog	Ebook-centric	Paper, ebook and audiobook cards together
Built-in ebook viewer / news downloads	Yes	No viewer on purpose — one click opens Calibre Viewer, SumatraPDF, Kindle…
Import the other program’s library	—	Database → Import collection from → Calibre

What the import actually copies

Point All My Books at Calibre’s metadata.db (it lives in the Calibre library folder). The program does not need Calibre running. Across come: books, series, tags, ratings, comments, covers, and the paths to the book files.

Left behind on purpose: conversion recipes, news feeds, virtual libraries, plugin data, the content server. Those stay in Calibre. Your Calibre library is not modified.

Step 1. Install All My Books 6.1

Download the current Windows build. If Calibre is already on the PC, All My Books offers the import once at first start and fills in the database path for you. You can always run it later from the menu. Import into an empty collection the first time so you can check the result before mixing it with books you added by hand.

Step 2. Point at metadata.db

1. Menu: Database → Import collection from → Calibre…
2. Select metadata.db in your Calibre library folder. The default on Windows is often C:\Users\<you>\Calibre Library\metadata.db. If you use several Calibre libraries, pick the one you actually read from (Calibre: the library name in the toolbar, or Preferences → Change Calibre library).
3. Wait until the import finishes, then spot-check a few cards: cover, series, tags, and whether the ebook file opens.

Step 3. Check file paths — do not delete the Calibre folder yet

After import, ebook files still sit in the Calibre library tree. All My Books stores the path; it does not copy the file. If you uninstall Calibre and wipe that folder, the links in the catalog break. Keep the library where it is, or copy the files somewhere permanent first, then update paths / rescan.

Prefer to catalog folders that were never inside Calibre? Skip import and scan ebook folders in place instead.

Step 4. Add what Calibre never tracked

• Paper books: Ins / Book → Add…, search by title or ISBN. 6.1 can also scan an ISBN with a webcam.
• Shelf location while the book is in your hand (living room / box B).
• Loans: mark a book as lent (F12); Tools → Loan history shows who still has it.
• Reading log and notes — see keeping track of books you read.

When to keep Calibre installed

Leave Calibre on the machine if you still need it for:

• Converting one format to another before sending to a Kindle or phone
• News / RSS to ebook
• The built-in viewer, if that is how you actually read

In All My Books, one click still opens the file in whatever reader Windows associates with that extension — including Calibre Viewer, if that is the association.

Quick FAQ

Will this change or empty my Calibre library?
No. Import is read-only on Calibre’s side. Calibre can stay installed.

I have several thousand books. Does the free mode fit?
The unpaid catalog is capped at 100 books. Import the library to see that the cards look right, then license the program if the collection is larger. Details are on the purchase page.

Do I need Calibre installed for the import?
No. You only need metadata.db (and the ebook files if you want to open them from the catalog).

What about duplicates if I already scanned folders in All My Books?
Import adds to the collection that is open. Use an empty database first, then merge later if you know what you are doing. Support can help with a messy overlap — contact form.

Coming from Booknizer, Book Collector, Alfa…?
Same menu, different file. See Booknizer, Book Collector, Alfa eBooks Manager.

Try the import

Install All My Books 6.1, accept the Calibre prompt (or pick metadata.db yourself), open a few ebooks from the catalog, then add one paper book by ISBN. If that is faster than maintaining two lists, you are done.
