Moreover, there is a decent textbook entitled "Gene Cloning and DNA Analysis: An Introduction", which should also help you. (if I remember correctly, a pdf of an older version can be found somewhere on the web).

There's a site called EcoliWiki that's useful. However, it does take some know-how to find most of the useful information:

The 'Plasmid' Section contains information about numerous elements common ion research and commercial plasmids:
