Rip all your favorite audiobooks from libby!

^{Powered by FFmpeg.js}

^{Be careful, I have had multiple library cards banned in the past from using this tool (See #14, #12, and #8 for more details)}

How to use

1. Install the TamperMonkey extension for your browser.
2. Install the userscript from the GreasyFork page
3. Find your audiobook on Libby and export.

NOTE: If you do not see anything, it could be because TamperMonkey is not set up properly on Chrome (and chromeium based) browsers! See the TamperMonkey FAQ page here for more info.

Using the Python Script (bakeMetadata.py)

This repository includes a Python script that allows you to bake metadata into your downloaded audiobook MP3s, either via the command-line or a GUI.

Script Requirements

Python 3.x is required, along with the dependencies listed in requirements.txt. Install them using:

pip install -r requirements.txt

Running The Script

You can run the script in either CLI mode or GUI mode, depending on your needs:

Command-Line Mode

python bakeMetadata.py [<audiobook_directory>]

• If no directory is passed as an argument, you will be prompted to enter one.
• This mode is ideal for batch automation or terminal workflows.
• Output, progress, and errors will appear in the console.

GUI Mode

python bakeMetadata.py --gui [<audiobook_directory>]

• Launches a PyQt5 graphical interface.
• If no directory is passed, you'll be prompted to select one with a file dialog.
• All output and errors (including warnings like Lame tag CRC check failed) will be shown in a scrollable status window within the GUI instead of the terminal.
• Useful for users who prefer a more visual interface.

What The Script Does

This script does the following:

• Loads the metadata exported with your audiobook from Libby (metadata.json).
• Embeds chapter information and cover art into each Part *.mp3 file using the eyed3 library.
• Sets ID3 tags including title, artist, album, and track number.

Notes

• The audiobook directory must contain a metadata subdirectory with metadata.json and a cover image.
• The script assumes filenames follow the Part X.mp3 naming convention.
• The message Lame tag CRC check failed is a harmless warning and can be safely ignored. It is now shown in the status window when using the GUI.

Note on EPUBs

The EPUB downloader is unstable, and unreliable. It works with a majority of books, however Libby does some processing to the xhtml before it is sent to the client, so that needs repaired, and this is not perfect, in addition I have no experience with the EPUB format. I am always open to contributions, so if you find an issue and want to fix it, please do.
