Latin
"Textkit began in late 2001 as a project to develop free of charge downloads of Greek and Latin grammars, readers and answer keys. We offer a large library of over 180 of the very best Greek and Latin textbooks on our Ancient Greek and Latin Learning pages. Since that time we have distributed millions of PDF textbooks free of charge world-wide."
"CSCP is a research and development project established in 1966 with funding from the Nuffield Foundation and the Schools Council. Unlike many Classical organizations, we do not charge a membership fee and have no members in the traditional sense, although many Classics teachers have been involved in the creation of our materials and the majority of UK teachers and students of Classics benefit from our work on a regular basis. Over 90% of secondary schools which offer Latin use our Cambridge Latin Course and our website receives over 80,000 visitors every week."
