A handy, simple and rough quide on the very common species trough the main characteristics on the pages of the Natural History Museum of London. Click on the "identification key". It's very good for beginners, I think.

There was also a survey on Isopod species in England, you can find info on the results, too.

This open-access article includes a useful "Key to North American Genera of Sand-Burrowing Taltridae" - the key is somewhat technical (you have to know the names of the body parts).

For talitrid amphipod morphology, the following paper (also open-acces) gives a great introduction to the morphology, even though it is not focused on the North American fauna:
