I dont have access to a stud book .
I get my information from media sources , emailing zoos directly , talking to keepers on zoo visits , zoobooks , websites etc
I will be the first to admit that I dont always get it right , but that is one of the good things about this forum -- someone can often revise information more correctly .
One of our members , Paul , is slowly building up a website of zoos worldwide . But it may be several years before there is much information available on internet about zoos in many countries , or at least in English/French/German . I can read Korean script , but I am not fluent enough to make much sense of it . And like most of us on this forum , I cant read Thai, Russian , Japanese , Chinese , etc
