Re: Using Perl to Query PubMed

[derby]

The folks at NCBI (part of NIH) have a web api called entrez that you can use to search then fetch pubmed articles (among numerous other NIH databases).

Update ... should have mentioned, a lot of their examples are in perl

[Shuraski]

Definitely use entrez tools, no need to re-do this on your own.
Another good tool, also Perl-based, is PubCrawler. It "goes to the library, while you go to the pub."
