Sources on the Peloponnesian War

I have to write a research paper about, well, anything I want, for my english class. I really want to write it about the Peloponnesian War, specifically the second Athenian expedition to Sicily, but my teacher is requiring me to have a least ten sources to cite and I don't have that many. My school's library has very few books about the time period. I was wondering if anyone of you knows of some good books that are easy enough to find. Obviously there's Thucydides, and I also have a book entitled Athenian Democracy and Imperialism by Loren J. Samons. I've also seen a book at a store called A War Like No Other Other by Victor Davis Hanson. I'm not sure if it's any good though. I'm sorry if this doesn't have anything to do with the mod, but I figured that the historical geniuses at the EB forum would know a lot about researching.

There are tons of books written on it actually. Primary sources are Thucydides of course, and Xenophon, as well as Diodorus Siculus. Secondary sources include all those D. Kagan books on the War (four or five I think) as well as any number of other modern books on it. Ste. Croix's Origins of the Peloponnesian War is very influential and important too. And Kenneth Dover's Thucydides is good too as is VJ Hunter's Thucydides, the Artful Reporter.

There are also a number great Athenian inscriptions from the war. You can get english translations of some of them from the first volume of Translated Documents of Greece and Rome, Archaic times to the end of the Peloponnesian War. The person who did the translations is Charles Fornara and I think the book would generally appear under his name. If not his than Robert Sherk the editor of the series.

Thanks Teleklos and Qwerty, your advice has been very helpful. Donald Kagan's series was especially helpful.
