from the BioMail Home Page: "BioMail is a small web-based application for medical researchers and biologists. It is written to automate searching for recent scientific papers in the PubMed Medline database. Periodically BioMail does a user-customized Medline search and sends all matching articles recently added to Medline to the users' e-mail address. HTML-formatted e-mails generated by BioMail can be used to show selected references in medline format, which is compatible with EndNote reference manager." You can either download and run it at your site or get an account on their server...

as seen at freshmeat: "Gutenbook is a personal multi-stage project to design, prototype, and develop a GTK+-based desktop application for reading Project Gutenberg Etexts. Currently, development consists of advanced prototyping in Perl/GTK+." According to the author, Lee, this is the original codebase from which the other Gutenbook project started, but this one is purely focused on perl/gtk+ instead of multiple (incompatible) codebases.
