Zotero is open source and the code for various parts can be found at https://github.com/zotero/. I think for the extraction the Translation Server is the key. It can be found at https://github.com/zotero/translation-server. Also the Zotero page has its own forum (https://forums.zotero.org/discussions) and I think they are usually quick to respond. Greetings Tobias PS: There is also the little less known zoterobib (https://zbib.org/) that might be interesting for some use cases (frontend and backend are also at Github). PPS: The browser plugin is at https://github.com/zotero/zotero-connectors (but I still think the Translation Server is what does the hard work. But I very well might be wrong :)) On 2020-04-14 02:20, Mark Weiler wrote: > The Zotero browser plugin seems to have the ability to extract metadata (e.g., author name) and PDF from a publisher's page. > > From a screen reader perspective this is helpful as it avoids having to learn how to navigate publisher's pages. > > Anyone have time to talk about how this done via phone? > mark
