Eric R. Guiler

Personally, I think Dr. Eric Guiler is one of the best authors for imformation on the thylacine. He keeps things nice and simple without talking down to the reader.
This book makes for a nice coffee-table book. It has excellent pictures, but is slightly lacking in some of the more obscure information (hence it only gets a 4 star rating.) He also updates plenty of information from his previous work.

Some of the information is a bit dated, but this is still an excellent book for information on all counts. One of my "Top 5" best books on the thylacine.
