A Guide to the Web's Best Sites by Mary Campbell and David Campbell. In many cases, it is a matter of taste and interest. The intent of this book is to help the user find those worthwhile URLs. The sites they include are mega-sites, that is, they include many links to other sites. Other than that, the criteria for inclusion isn't all that clear.
Some entries have fairly substantial annotations, others a mere sentence or two.
The more complete ones are well-written and give the user a good idea of site content. Mostly this book suffers from unevenness, sparse pointer references, and poor indexing. It is a good start and could very well improve with future editions. Online Inc. All rights reserved.
