The Foreign Service Institute has a fairly plain and simple web site, but it offers a wide variety of language courses for free. Both texts (PDF files) and MP3s are offered. There are, for example, 72 lessons for Greek and 40 for Hebrew. It is modern language, of course, and the texts are rather old (1967 for the typewritten Greek), but they may be useful. (Where else will you get Amharic instruction?) Here's the site description, and the list of languages offered. UPDATED LINK: FSI Language Courses
