Favorite caresheet and book recommendations, please

[eyespy]

A friend of mine is interested in getting a cornsnake and started asking me questions about them. I'm a former veterinary surgical tech so I know a lot about their health, but not so very much about specific husbandry requirements. I know they are very hardy, relatively easy to feed, and quite beautiful and would make a good first snake for my friend.

I'd appreciate hearing about your favorite sources for husbandry info that I could pass on to Chris.

Thanks in advance.
