EDD is an ILL tool written in VB5 for managing the automated conversion of ARIEL files to web-accessible pdf files. See the EDD project page for source, binaries, and more.
Both the Ecila (French) search engine codebase, catalog-1.0, and the U.K. eLib endproduct ROADS v2+ are open source and increasingly used tools for building web-based catalogs a la Yahoo. Some eLib folks have explicitly turned to open source as a way to keep formerly well-funded projects going (see the press release describing this decision). Open source as "exit strategy" isn't terrifically sustainable, but a step in the right direction nonetheless.
from the Gutenbook site: Gutenbook is an app for downloading, and reading of etext books published electronically from the Gutenburg Project. it's fairly basic but it works, and has ports for linux (tk or qt) and windows. not only is this a needed app, it looks like a great starting point if you are interesting in learning to hack one of these environments (gtk-perl or kde/qt).
as seen at freshmeat: "iManager is an easy-to-navigate image manager with some extended features. It allows you to manage your family album or a big collection of images." it's kde/qt-based, so i can't try it myself. what do y'all think?
If you're a librarian and you haven't thought through what napster means yet, get thinking. Many folks are perturbed about how easy it is to violate copyright using napster.

Ovid Statistics Log Report Generator is a perl script that produces usage reports from Ovid log statistics. See the project page for more.
seen at freshmeat and from the site: "pybliographer is a tool for managing bibliographic databases. It currently supports BibTeX files for reading and writing, and can also read Ovid files... It can be used for searching, editing, reformatting, etc. In fact, it's a simple framework that provides easy to use python classes and functions, and therefore can be extended to any usage (generating HTML pages according to bibliographic searches, etc)."
as seen at freshmeat: "Etext string searches are now working. Added CREDITS, MANUAL files. Cleaned up the Makefile. Refined the keybindings. Init method looks for .gutenbook and Gutenberg_Library directories; makes them if they don't exist. This in preparation for implementing user preferences UI and saving etexts locally." all this and more available at the Gutenbook site.
