This article regards the LacusCurtius website, named after the Lacus Curtius in the Roman Forum.
LacusCurtius is a website specializing in ancient Rome, currently hosted on a server at the University of Chicago. It went online on August 26, 1997; in January 2008 it had "2786 pages, 690 photos, 675 drawings & engravings, 118 plans, 66 maps."
The main resources to be found on it include:
a number of Latin texts, usually in the original Latin and in English translation
a photogazetteer of the Roman remains of central Italy
The parent site also includes a large American history section and a Gazetteer of Italy; the latter is somewhat of a misnomer, being almost entirely about central Italy, especially Umbria, for which it is a useful source.
The proper spelling of "LacusCurtius" is as a single CamelCase word, with no space; the idea was to avoid polluting searches for the Lacus Curtius, a different thing altogether.
