I have spent an inordinate amount of time during the past 13 years developing a comprehensive literature database for trilobite papers. At this point we are nearly at the goal of having the entire trilobite systematic literature both keyworded for taxa and available as text-searchable pdf files. This means that one can, for example, find every mention in the literature of a particular genus or species in seconds with a single Spotlight search in OS X. This resource is shared by everyone in the lab and the main database resides with our online data. Beyond being a valuable tool for systematic research, we are exploring publication patterns in the history of trilobite research.
A more ambitious project is the development of a species level relational taxonomic database for all of Trilobita. This is now "finished" in the sense that I'm confident I have at least 95% of all published trilobite species entered. A recently published tabulation of diversity puts Trilobita at 165 families, 3,919 genera, and 20,859 valid species. Now that the database is in a usable state, the numbers of analytical studies possible is vast. Click the link for some of the works in progress.
