At university, my supervisor used to say that he would always read the references at the end of a research paper first. His reasoning was that this gave you an easily skimmable indication of both the coverage of the paper and its influences. I'm not sure that many people share this attitude, but if you do, you'll be interested to see that I've put both of the Notes and the Bibliography of Net, Blogs and Rock'n'Roll online.
It's probably more likely that you'll find these useful if you're one of the growing masses who have read the book, and would like easy connections to the articles and books that I mentioned in it. The notes are all hyperlinked, so you don't have to copy out URLs from the back of the book, just click the link to go there directly. Ditto with the bibliography, which has links to further details of each book on LibraryThing and Amazon.com.
