Beckon Books is one firm that has begun publishing guidebooks for American zoos and aquariums although they do not sell their products directly from their website. I've already purchased the new guide for New England Aquarium (on my last road trip) as well as the trio from sunny California of San Diego Zoo, San Diego Zoo Safari Park and San Diego Zoo: Panda Trek via the Safari Park's online store. I also ordered Cleveland Zoo's commemorative guidebook and I'm debating what to do about the Philadelphia Zoo publication as the price is reasonable but shipping to Canada can at times be extremely expensive. My question is this: has anyone already purchased the Philadelphia Zoo book, or pre-ordered upcoming releases profiling the Phoenix and Riverbanks zoos? I'd be intrigued to know about the quality of the publications as after years of a fairly dormant book scene in terms of guidebooks there is suddenly a plethora of zoo-based literature being published. Some covers of new guidebooks are showcased here: Beckon Books Riverbanks Zoo's 40th Anniversary Book ($40 hardcover or $20 paperback): http://society.riverbanks.org/document.doc?id=57 The "Images of America" series is up to at least 14 zoo-based books and I've purchased all of them as what they lack in textual information they make up for in terms of historical photographs. Here is an example of one book in the series, and this one is of the Oklahoma City Zoo: [ame=http://www.amazon.com/Oklahoma-City-1902-1959-Images-America/dp/0738540498/ref=sr_1_1?ie=UTF8&qid=1384800635&sr=8-1&keywords=oklahoma+city+zoo]Oklahoma City Zoo 1902-1959 (OK) (Images of America): Amy Dee Stephens: 9780738540498: Amazon.com: Books[/ame] Phoenix Zoo's 50th Anniversary Book (to be published any day now) is one that I'd also definitely order if shipping and handling was not outrageous. My bank account is beginning to groan.
