-
sra-own.bib: All publications that were authored by members of the group. This file contains no @crossref entries. All @proceedings entries are actually workshops or conferenceses that were edited by an SRA member. -
sra-ext.bib: Shared bibliography file of all further refrences. This file makes use of @crossref entries (albeit not systematically).
Note The SRA bibliography itself is hosted at github at https://github.com/luhsra/bib.git. You may have found, however, this file somewhere on your local disc. If that is the case, it is very likely that you have found it in the local checkout/clone of some other svn/git repository, where it is embedded via git-submodule or svn:externals.
