Pawped's Historic Archive on the Maine Coon

on the "Pawpeds"-website -  wellknown for the database where we can see and research and testmate pedigrees of over 16000 Maine Coons from the very first registered ones on -  you can research through a quite big section which is beholden to our breeds history, collecting articles, interviews, cattery presentations :

So we can find a section on the Maine Coon Ancestors - including the Methusalem-list of breeding cats who got over 15 year old : ,

and a section where you find a collection of all the interesting historical informations on our breed, the
Maine Coon Heritage Site 

Interesting also, and highly recommendable is the course system, that pawpeds offers to  fanciers and especially breeders of cats:
