Marian The Librarian Firefox

Marian The Librarian

Extracts book details from supported book detail pages like Amazon, Goodreads, The StoryGraph, and more. Created for the fine librarian corps of Hardcover.app.

Features & Capabilities

Shhh... this is the first official release of Marian, a browser extension to make copying book / edition data from various platforms a little easier. Made with the lovely Librarian Corps of Hardcover.app in mind.

The functionality is simple: Parse the current page (if the site is supported) and pull out the data that's relevant to Hardcover librarians and supporters. It formats and orders the data to match the Hardcover Edition edit form and makes copying values as easy as a single click. No more scrolling up and down Amazon listings. You can download full-sized images with a single click as well.

For now, the extension works on Amazon book and audiobook pages, Goodreads, The StoryGraph, Google Books, and more to come. Other suggestions are welcome, just open an issue on GitHub.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Marian The Librarian is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
