Downloads a .xpi file (0.04 MB). In Zotero, open Tools → Plugins and install it from the file.
In useAn estimate of how many copies of Zotero have it: Zotero downloads each new version once for every copy that has the plugin, so we count the downloads of its most-downloaded recent release. Rounded. Plugins that update from outside GitHub count low.
48
DownloadsAll-time downloads of its release files from GitHub, counting every update. Installs from elsewhere aren't counted.
49
ReleasesVersions published on GitHub. Everyone who has the plugin downloads each one again, which adds up in Downloads.

What it does

Written by AI from the README

Click an in-text citation in Zotero's PDF reader to see the cited paper's title, authors, abstract and links in a card styled like Google Scholar's. It uses Google Scholar when you sign in, otherwise OpenAlex.

Checking a reference normally means leaving the PDF to search for it. The card shows the cited paper right where you read.

Your rating of Citation Cards v0.1.1

Your review is public, under the name you give, and published with the directory's data under CC BY 4.0. Links are removed. We never store your IP address: a scrambled code made from it is kept for 30 days to catch fake reviews. Every review is checked before it's published; how fake ones are spotted isn't published, so it can't be gamed.
