JAbbr is an online tool that helps decipher journal title abbreviations. (It also works for conference proceedings and other serial publications.)
Given an abbreviation, JAbbr tests it against a list of serial titles extracted from the library catalog, and uses fuzzy matching to return a list of possible matches.
JAbbr currently uses data extracted from the Cornell University Library catalog. If Cornell doesn't have a particular journal, then JAbbr won't find it.
JAbbr was developed by Keith Jenkins, a librarian at Cornell University's Mann Library. Many thanks go to other Cornell librarians and staff who have tested JAbbr, provided feedback, and suggested improvements.
