4.6 Database Subsets
====================
RefTeX offers two ways to create a new BibTeX database file.
The first option produces a file which contains only the entries
actually referenced in the current document. This can be useful if the
database is only meant for a single document and you want to clean it of
old and unused ballast. It can also be useful while writing a document
together with collaborators, in order to avoid sending around the entire
(possibly very large) database. To create the file, use ‘M-x
reftex-create-bibtex-file’, also available from the menu under
‘Ref->Global Actions->Create Bibtex File’. The command will prompt for
a BibTeX file name and write the extracted entries to that file.
The second option makes use of the selection process started by the
command ‘C-c [’ (
Creating Citations). This command uses a
regular expression to select entries, and lists them in a formatted
selection buffer. After pressing the ‘e’ key (mnemonics: Export), the
command will prompt for the name of a new BibTeX file and write the
selected entries to that file. You can also first mark some entries in
the selection buffer with the ‘m’ key and then export either the marked
entries (with the ‘e’ key) or the unmarked entries (with the ‘E’ key).
