Checks for free PDFs from Google Scholar, Sci-Hub, LibGen, Anna's Archive, Sci-net, Semantic Scholar, Unpaywall, OpenAlex, Openrxiv (medRxiv/bioRxiv), and ArXiv. When hovering a DOI, it also displays journal name, ISSN, publisher, metrics (SJR, H-Index, JIF, CiteScore), citation count, and integrity status (PubPeer, Retraction Database, Beall's Predatory List).
This script is an all-in-one toolkit that supercharges your research workflow. By simply hovering over any link containing a DOI, you get an instant, feature-rich popup with three crucial categories of information:
Free PDF Access: Instantly find free PDF versions from over 10 sources, including Google Scholar, Sci-Hub, LibGen, Anna's Archive, Sci-net, Semantic Scholar, Unpaywall, Openrxiv (medRxiv/bioRxiv), and ArXiv.
Journal Quality Metrics: Assess journal quality at a glance with key indicators like SJR, H-Index, and Journal Impact Factor (JIF), helping you understand the publication's prestige.
Academic Integrity Checks: Make informed decisions with crucial integrity data. View PubPeer comments, check for retraction status from the Retraction Watch Database, and receive warnings for journals on Beall's Predatory List.
Designed for efficiency, the popup only appears on hover to minimize network requests. It's an essential tool for any researcher, student, or academic looking to streamline their literature review and critically evaluate sources on any website.
