BibTeX, biblatex and biber ⇒ Automatic "extraction" of literature entries?

[tjaenare]

Hello everyone,
I am almost sure that I conducted my search with the wrong search terms as I hardly can imagine that there should not be anything like this.
Here is what I am looking for: I am using one, rather large bib-file. This is convenient when working in different projects and you have access to all your literature entries. Now I need to share the entries of a particular project (no separate group in the reference manager). And there is the final report of that project, which accesses this file.
Is there any way to simply identify or automatically extract all the literature used in the report into one bib-file?

I am using biblatex with biber and JabRef as the reference manager. If there is any other way in the combination biblatex and bibtex I could simply swith for this exercise. Thinking of manually exporting some 1,200 entries, however, is not exactly what I would like to do...

Thanks a lot in advance!

As so far no ideas have have come in, I have taken the liberty to also post it at another forum.

Thanks for the crosspost information! I read the suggestion there too.

By the way, there is another German language TeX site: http://texwelt.de It's a question & answer site, so different to a forum. Not really a need to crosspost there too, since the users may be the same but it's another format than can be more appropriate sometimes. It allows better archiving and sorting by topics and quality.

For those who are interested in the solution, which was suggested here: http://golatex.de/viewtopic,p,91750.html

Using biblatex with the backend biber it is easy to use biber with the proper output-format. After the first ordinary run of LaTeX biber is called in the following way:

Code: Select all

1
biber --output-format=bibtex test-file.bcf

(cf. paragraph 3.1.1 in the biber documentation (biber)). This results in the file test_biber.bib.
This procedure worked perfectly for me!

Another possibility for those using bibtex was suggested: In this case, bibexport can do the trick. Have not tried it myself, but thought to mention it for the sake of completeness.

Thank you, Stefan, for the hint! Sounds promising! So, next time I will give http://texwelt.de a try!
