A repository of abbreviations for references, e.g., for conferences, journals, institutes, etc.
JabRef can help you refactor your reference list by automatically abbreviating or unabbreviating journal names. This requires that you keep one or more lists of journal names and their respective abbreviations. To set up these lists, choose Options -> Manage journal abbreviations. See also https://help.jabref.org/en/JournalAbbreviations.
Currently, only journal lists are offered.
Now the data files are in CSV format (using semicolons as separators):
<full name>;<abbreviation>[;<shortest unique abbreviation>[;<frequency>]]
The two last fields are optional, and you can actually safely omit them.
JabRef supports the third field, which contains the "shortest unique abbreviation".
The last field is not currently used; its intention is gives frequency (e.g., M for monthly).
For instance:
Accounts of Chemical Research;Acc. Chem. Res.;ACHRE4;M
This was done in old versions of the "general journals list" primarily because the information was available. In the current version shipped with JabRef (https://github.com/JabRef/jabref/blob/master/src/main/resources/journals/journalList.csv), this is not the case any more.
