This is an add-on for Zotero, a research source management tool. The add-on can auto-fetch DOI names for journal articles using the CrossRef API, as well as look up shortDOI names using http://shortdoi.org. The add-on additionally verifies that stored DOIs are valid and marks invalid DOIs.

Please report any bugs, questions, or feature requests on the Zotero forums.

Code for this extension is based in part Zotero Google Scholar Citations by Anton Beloglazov.
