The Perseus Project
http://www.perseus.tufts.edu/
It has entered most classical texts online both in the original
Greek/Latin, as well as with translations and commentaries. In addition,
the site has various very useful features, including a built in
dictionary (click on any Latin word to see the Lewis & Short entry),
various classical encyclopedias, and powerful intertextual search
features.
Whitaker's Wordshttp://users.erols.com/whitaker/words.htm
It's a downloadable Latin-English dictionary. It has a text-based
interface into which you can type any Latin word, declined or conjugated
however, and it will tell you all the possibilities - it makes
translating texts much easier, as it's quicker than leafing through the
dictionary for every unknown word, and it also speeds up parsing (be
warned, it may stunt your learning of grammar if you are not careful).

section is pretty well populated as well. If you want a map involving
Texas they've probably got it."

Modern
http://www.fordham.edu/halsall/mod/modsbook.htmlThere are further smaller source books drawn from subsets of these larger
ones for African, East Asian, Indian, Islamic, Jewish, Global and
Women's history, and the history of science. Some of the translations
are relatively old and many have been supplanted by newer versions, but
none of them are so old-fashioned that they're unusable.
