References to classics journals are often abbreviated in citations. The meaning of the abbreviations can often be found with a quick google search, but sometimes the more obscure references can’t easily be found.
There’s a really useful list of abbreviations in this book, which is now available online from the Library’s website: Dictionary of Bibliographic Abbreviations Found in the Scholarship of Classical Studies and Related Disciplines, by Jean Susorney Wellington.
It’s a comprehensive list, and although a little clumsy to use is well worth your while. First of all, look up the abbreviation in Part I: Abbreviations eg ABSA. That will give you an index number eg ABSA: A425 which you can look up in Part II: Bibliographic Descriptions. (You might find it better to click the blue ebrary Reader button, and then under InfoTools, Search Document.)

As you can see, this is just a reproduction of the printed dictionary. This would have been much more convenient as a searchable database, or at least with hyperlinks from the abbreviations to the definitions, but at least you can find the answer in here!
If you happen to be in the Library, the printed book is in the Arts Reference Collection on Level 1 (483.1 W45 2003)
There are even more resources for journal title abbreviations on this webpage.
