To celebrate 50 volumes of the International Zoo Yearbook, a virtual issue with papers from throughout its history is open-access for a limited time. International Zoo Yearbook - Virtual Issue 50 Volumes - Wiley Online Library
It appears that you can only read the abstracts(introductions) to the articles on here- the main arrticles are masked and you can either rent them for 48 hours, or buy them, in each case a fee is involved. If anyone manages to read them online without subscribing,do let me know!
It should be free to access and I don't have any problems reading the full articles. Perhaps you need to set up a Wiley account, which doesn't cost anything.
The different papers seem to open fine, without an account. As with the IZY itself, they're a rather odd bunch: breeding mealworms, the conservation of wild horses and the history of the yearbook itself (amongst other things).
