The Library of Latin Texts (LLT) started in 1991 as CETEDOC Library of Christian Latin texts (CLCLT), in CD-ROM and then DVD-ROM. In 2002 the name was changed to LLT as it included classical and post-classical Latin texts. In 2009 it split into two different online resources:
- LLT-A is the direct continuation of the previous project, including digital editions of Latin texts mostly taken from Teubner editions and published with an accurate philological revision by CLTLO (formerly CETEDOC) under the direction of Paul Tombeur.
- LLT-B is meant as a more fast-growing supplement to LLT-A. The texts of LLT-B are drawn directly from printed scholarly editions while much of the revision work is dropped and precedence is given to large, homogeneous corpora of texts.
The two collections do not differ in time scope (spanning from Classical antiquity to Neolatin texts until 1965, including decrees from the Vatican II Council), but in publication practices and philological standards. The quantity of texts and their overall philological quality are outstanding. Access to the collections, however, is granted by paying a subscription fee through the Brepolis platform (more information on the collections is in their Database information page).
- The LLT-A as of 2012 contained over 63 million Latin words, drawn from more than 3,200 works that are attributed to approximately 950 authors.
- The LLT-B began in 2009 with 7 million words and expected to add new texts of 4-5 million words per annum.
