Persian leopard library is updated with new papers and reports on the animal. It is composed of more than 40 documents about the Persian leopard in English and German which are all available to download on the ICS website. Launching and maintaining the library is one of the main activities to celebrate the “Year of Leopard” in Iran to help researchers and biologists. One of the recent documents is Zukowsky’s report in early 1960 about description of the leopards’ subspecies in west Asia. The library is easy to access through clicking on the “Year of Leopard” in left main bar on the homepage.
