About ISAAC Chrome extension

Browser extension that helps adding resource output to the NWO ISAAC database. After selecting the type of "product", the extension pop-up dialog can be used to look up metadata using DOI, PubMed identifier, and ISBN. The extension supports adding authors will jump to the "add author" iteratively, allowing you to add additional information (ORCID/gender/DAI). The plugin uses citation-js, see https://peerj.com/articles/cs-214/ while the source code is available from https://github.com/citation-js/isaac-chrome-extension under the MIT license. Information is collected from Crossref, DataCite, and mEDRA (DOI), Google Books and OpenLibrary (ISBN), PubMed (PubMed identifiers) and Unpaywall (OA status). THIS IS NOT A NWO ENDORSED EXTENSION AND NWO HAS NOT BEEN INVOLVED IN THE DEVELOPMENT. BETA: this extension is early in its development cycle. All feedback is welcome. Use at your own risk.
