Having a BibTeT file with full journal titles in it, I'm looking for a tool to construct a list of abbreviations following ISSN standard (it specifies how to abbreviate individual words, which should make it straightforward to generate abbreviations for any title). I'm ware of JabRef, but it requires a list of title-abbreviation pairs and I don't want to do one by hand if I don't have to. (I should add that the lists available from JabRef website do not cover the titles I have).
math reviews/mathscinet has a list, abbreviation of names of serials, in the form of a pdf file. there's also a corresponding csv file suitable for use with excel. not precisely what is requested, but perhaps useful nonetheless. i don't know whether is follows the issn standard to the letter; mr established many of its abbreviation principles before issn existed.
