These sources will help you find abbreviations for journal titles. They will also help you find complete journal titles when you have only the title abbreviations.
SU Libraries offers the BrowZine tool for locating available journals in your field by title or subject.
If a journal you need does not appear in BrowZine, here are two additional places to check:
1. Search the library's complete holdings of all print and electronic journals, go to the Journals A-Z list. Enter the journal title, and search.
2. WorldCat Discovery (WCD) also shows both the print and electronic journals in the library's collection. In Advanced Search, enter the journal title into the Title box and search.
