pmid2bib produces a nighly-formatted BibTeX entry given a PubMed identifier (a PMID). You have to add the CITEKEY yourself (e.g. Crick61). You may need to do some light editing of things that the script isn't smart enough to do. For example, check for accented characters on authornames, capitalization and italics (species names) in titles, and your preferences for journal abbreviation.

The pmid and reprinturl fields in the entry are noncanonical custom fields that I use in my own .bib files.

The script is rudimentary, with rudimentary rules. The goal is to get something close enough to save a lot of typing time, not to get every detail.

The script uses urllib.request to obtain an XML entry from PubMed, and xml.etree.ElementTree to parse that XML. The script also doed some light rule-based stuff to format the author names as initials/surname (as "X. Y. Foo and A. B. Bar and Z. Baz"), standardize capitalization in titles (including recognizing some common species names to leave them uncapitalized - but you'll need to add the \emph{} italics yourself), and switch in some of our most commonly used journal abbreviations.

See the source code of the script itself (which is brief) for more detail on what and how it's formatting.
