English Shepherd Club Registry Online Database - hands down the most valuable website for people interested in researching dogs in the breed. The online database is open to the public and includes pedigree information, photos, health information, and owner descriptions of dogs. Wonderful, wonderful resource. Any English Shepherd owner can submit information to be included in the database; old family photos and records are particularly valuable. Contact the registrar for information.
The English Shepherd website -- general breed information plus information on litters available, working dogs evaluations, upcoming events, and more.
Herding on the Web - outstanding collection of information on herding breeds, their history, and more.
Working Aussie Source - notable for many things but in particular check out the Stock Dog Library, which has a great collection of articles on training, and the Working Dog Diary.
