I agree with Jim that not having an index allows one to practice learning the order of the species. I also think that it is easier to leaf through less than 50 pages than an entire field guide, but I don't believe it would be that much effort to allow folks a choice. Rob and I could just ignor the back cover. Good Birding, Patty Craig Dameron, St. Mary's County, MD pattycraig@mail.ameritel.net
