Eric Schnell [1] writes in that "Prospero for Windows 2000/NT/98/95 [2] is a web-based document delivery system designed as a compliment to the Ariel software system [for ILL over the net]... [it comprises] a staff module which captures and converts Ariel files to Web accessible documents... [and a] server-side user interface which allows patrons to retrieve their documents using a web browser." It is GPLd and uses some of my code! This got a major wooh-hooh! from everyone here at Yale... or, well, at least a "why, that is quite exciting indeed."
