For years, the best collection of searchable texts from Latin antiquity was the Packard Humanities Institute PHI CD-ROM #5.3, available in the Digital Humanities Center in 305 Butler.  Getting these texts available online was the Holy Grail of digital classics research.

But now the Grail is at hand, as the Latin texts from PHI 3.5 are now online.  Approximately 350 authors, representing almost all classical literary texts up to 200 CE (with a handful of later authors) are now readable and searchable online.
