These are javascript scrapers that work on a large number of academic publisher sites and are actively maintained.

Paperbot offloads links to [zotero/translation-server](https://github.com/zotero/translation-server), which runs the zotero scrapers headlessly in a gecko and xulrunner environment. The scrapers return metadata and a link to the pdf. Then paperbot fetches that particular pdf. Also, sometimes in IRC someone drops a link straight to a pdf, which paperbot is also happy to compulsively archive.
