Those with an eye towards good Greek and Latin resources may be interested to note (if they don't know of it already) TextKit.com (hat tip: Bernard of L'Abbe Faria's Cell)
One of the things about the classics is that while new things are said about them, they themselves have remained much the same for some time. And indeed, some of the best texts on learning Latin and Greek are getting quite old at this point.
The folks at TextKit have been scanning in classic Classics texts and making them available in free, downloadable PDF format. I took a look at a couple of their texts last night, and they are definately clear and readable. Among the texts available for download are Smyth's Greek Grammar, Allen & Greenough's New Latin Grammar and a number of good classic schoolboy reading texts of Greek and Latin authors.
