Although I haven't advertised it well, there's also an API available for 3rd party use. Example request:

http://api.libroipsum.com/literature/cicero.json?words=100&#...

All sources:

http://api.libroipsum.com/sources.json

Supports JSON, JSONP, XML, and plain-text (TXT) - simply replace JSON with appropriate extension.
