How to Find Editions and Commentaries?

Is there any easy way to find out what your choices are for a particular text (with or without commentary)?

You usually know you can get a Loeb, but what else can you get? Right now I’m looking for a text of Polybius but I’m not sure how to establish what the possibilities are. Is there any quick way? Even if you search on amazon, it is not clear what to search for. Polybius alone gives too many results. Polybius Greek leaves out some stuff. Yada yada yada. And to make matters worse, I’d almost prefer non English commentaries.

The standard Greek edition of Historiae with notes (I don’t know how extensive they are) is that by Theodorus Büttner-Wobst:

http://www.amazon.com/Polybii-Polybius-Historiae-XX-XXXIX-Fragmenta/dp/B001KVM6VO/ref=sr_1_1?ie=UTF8&s=books&qid=1307243138&sr=8-1

But it’s hard to come by.

Thanks. I figured that out. You can get it from the publisher:

One can always do an hour of research and figure out what is available. I am leaning towards a French edition:

But, I would like to know some general way of learning what is available faster. The best I have come up with is searching:

author title bibliography site:.edu

And hopefully some professor has provided some good information for a course.

I’ve linked to this a couple times, suppose I should propose it for the resources thread as it’s helpful and most people don’t seem to know about it.
The Joint Association of Classical Teachers in the UK has a “good text guide” here: http://www.jact.org/publications/goodtext/goodtextguide.php
The idea is to provide a comprehensive list of available texts & commentaries of classical authors, oriented towards the needs of students rather than already experienced scholars. I’m not sure how complete it is (I didn’t see Polybius right off hand), and I think it’s limited to English-language commentaries, but it’s the only “go to” site for multiple authors that I know of.

Thanks. I’ll definitely add that to my favorites. Seems to be the only game in town. But no Aristotle either!

Aristotle is there–––13th up; above Cicero in the pull down menu.

Spiphany, good resource…thank you.
