The Mathematics Genealogy Project is maintained by the Department of Mathematics at North Dakota State University. The goal of this project is "to compile information about ALL the mathematicians of the world." It is soliciting information from anyone who participates in the development of research level mathematics or has information on mathematicians to include in the database. The site notes some of the challenges to this project such as imperfect data sources and the ways in which the model the project is using may be anachronistic for the earlier periods. Nonetheless, as of May 15, 2005, the project has amassed 86,827 records. The database can be searched by a variety of criteria, such as individual name, name of school, year of degree, country, math subject, or key word from a thesis.
