As I generally do with a subject I don't know much about, I started with a quick search on AltaVista and found a number of useful links:
A search in MathSciNet for 'genetic algorithms' returns more than 400 references from the mathematical literature.
A subject search for 'genetic algorithms' in the FirstSearch Applied Science and Technology Abstracts returns over 500 items
A page of links to IEEE Journals makes it relatively easy to search their contents, title by title.
Search the ACM Digital Library
And results of a search on ANNIE
