I have Clint Eccher's "Professional Web Design" (2008), and I have found it useful, so I thought that "Advanced Professional Web Design" (2007) would take up where that left off. Instead, three-fourths of the content of the "advanced" book is simply a duplicate of content from the other book. Given my expectation, I was quite disappointed. There are a few chapters beyond the "basic" book that cover database driven sites, but the examples and templates are the same.
You may find one or the other of these two books useful, but the amount of overlap and outright duplication of content between the books is so great that you certainly don't need both.
