One of the classes I am taking this summer is on Ancient Greek Civilization. It's been a great class so far with some interesting reading. Last week I had to turn in a paper concerning how best to use the Greek historian Herodotus as a source.
If you're not familiar with him Herodotus mainly concerning the history of the Persian Wars in ancient Greece. In addition to that he has some great stories from the various Greek poleis that he visits or hears second-hand. There are critical editions of the text that you can buy, but I found that the Perseus Project's version are good and provide you both with a couple English translations as well as the Greek text. What is really nice if you're doing higher-level research is that Perseus allows you to click on a Greek word and it takes you to a Lexicon entry for that word. What really comes in handy is that the lexicon can show you other places that the word is used in any other Greek literature. For example, I was making a point in my paper concerning Herodotus' ideas of democracy and tyranny. I was able to them compare a particular word he used and see that Thucydides used the same word in a passage on tyranny, but used it in a slightly different way. It was a great comparison that would have been very difficult without the Perseus Project's cross-referencing ability. If you haven't read Herodotus, it's an interesting read. Just get a good translation. Some of the older ones try to make it sound like Herodotus was from Elizabethan England. Also, if you're doing any research in ancient history the Perseus Project from Tufts University is a good place to go for primary source material.
