Zoos have libraries. Go figure. I discovered this bit of information recently when I saw a job posting for an Associate Director of Library Services at the San Diego Zoo Global Library. The position closed to applications on October 11th, however here is the link to the job posting for anyone interested, and this is a link to a .pdf I've uploaded to Google Docs for posterity. The existence of libraries in zoos had never occurred to me. Then I realized, of course zoos have libraries. Zoos need access to veterinary collections for animal care, biological research, zoo history, current practice in animal care, to name a few needs.
I spent some time on the San Diego Zoo's library website and was impressed with the resources available. Check out these Fact Sheets. They are HTML pages that cover a breadth of topics. I dig the hippopotamus photo.
The zoo library has over 11,000 books and 400+ journal titles. There are archives and rare books, as well as general reference services and information. It looks like a great library resource. I borrowed some photos from the website to give you a look. Click the photos to visit the library home page.
