What's the best guidebook ever written

What in your opinion is the best guidebook ever written? Whether it's for the routes, writing style, photos, etc.

The Good, the Great, and the Awesome. Peter Croft is HI-larious

I can't say what's the best, but I'm pretty impressed with the two-volume "Adirondack Rock." Amazing amount of information, well organized, user friendly. I'm sure there others just as good, but I haven't seen any better. 

The new Yosemite guide book is beautiful. 

The Granite Guide has my vote. Massive selection of climbs and great history and stories to boot.

nice question. I think it depends on what qualities you want from a guide. If you want the latest routes with the clearest access and least history the modern guides and select guides are nice. SuperTopo comes to mind. If you want the history along with the stories, the Levine guide to Eldo is nice. Becky's got a series of guides for the Cascades and there was once a (3) set guide to the Gunks by Williams all of which are out of date but nice for the background. 

The black: rock climbing in the black

The original Desert Rock guidebook by Bjornstad is my favorite.  Out of date, out of print, full of vague or misleading information, but it is iconic and I treasure my copy.

The Limestone bible sucks

Patagonia Vertical Chalten Massif

Joshua Tree Central! JK I really like the minimalist style of Randy’s JT guides, so fitting for the area

+1 for the original Desert Rock.  Rare and hard to find, the only source of information for a lot of desert climbs (including now-illegal ones), and a classic book for a spectacular climbing landscape. Maybe the most coveted guidebook in the country?  I feel slightly guilty even opening mine to look through it.

Not going to declare a best, but I appreciate a guide that inspires me to do a route and without going into too much detail.

Adirondack rock is so detailed and organized it’s absurd. Well done. 

Cosumnes River Gorge guidebook.  .  

More of a hiking guide than climbing (although there some climbing routes in it), but one of the most entertaining reads in a guide book is Gerry Roach's Colorado Fourteeners.  It's filled with insight, great stories, and some rich humor.  

I’m liking ddriver’s thoughts.  Classic Dolomite Climbs - 102 High Quality Rock Climbs by Koehler and Memmel completely changed my outlook on places to travel to.  The book doesn’t give it away, but invites one to the adventure.  My trips to the Dolomites, because of this book and with this book, are some of the best memories of my 53 years of a climbing life. I’ve completely worn out several copies of that guide book.

John Sherman’s first Hueco Bouldering guide.

A half-inch thick sheaf of random, odd pieces of notepaper I got from a partner, with strange squiggle marks on each page and a word or two here and there, the occasional self-deprecating comment.

I won't say it's the best ever, but my personal favorite is "Ocean's Eleven: Bouldering Around Santa Barbara" by Bob Banks.  I'm a little biased, as it's the first guidebook I ever owned and it covers my home area, BUT almost 20 years later it still hasn't been knocked off the podium thanks in large part to the author's strong and humorous personality which shines shines through on every page. IMHO humor plays a big role in my enjoyment of a guidebook and Ocean's Eleven has it in spades.  Plus it recommends a different local burrito spot to hit after climbing at each area.

Shameless plug but if you like guidebooks you might enjoy one of these videos:
