Genetic linkage reference maps: access to Internet-based resources

The goal of this appendix is to introduce the reader to some of the most useful reference map resources now available through the World Wide Web (WWW). The maps presented in earlier versions of this appendix have been eliminated, since they are no longer updated and the most common methods of access and retrieval of up-to-date reference maps are now through the WWW. It should be noted that the very nature of the WWW is dynamic change. New sites appear and old ones disappear with somewhat disruptive regularity. The sites mentioned here are the most likely to remain stable, and thus to remain useful for the human gene mapper.
