Reconstructing “.bib” files
Perhaps you've lost the
.bib file you generated your document from,
or have been sent a document without one. Or even, you've realised
the error of building a substantial document without the benefit of BibTeX…
The Perl script, tex2bib makes a reasonable job
.bib files from
provided that the original (whether automatically or manually generated)
doesn't deviate too far from the “standard” styles.
You are well-advised to check the output of the script. While it will not usually destroy information, it can quite reasonably mislabel it.
Documentation of the script is to be found in the file
