In many fields there are a few books (or only one) that are simply the best-known (or even the best) general reference for that field. Just about everyone with some knowledge or interest will have heard of it, most would consider owning or having access to a copy a requisite for study of the subject. They are often so venerated and recognizable that only initials or a single name is used to refer to them. Few would find it odd if you wrote ‘OED’ in a sentence without explanation, and most would agree that a word not found there was likely never an English word.
Not every classic reference is as well-respected, and in some fields the material is growing old, even though the book will still be known and recommended. We’re talking well-known, not necessarily well-liked. So opinions are welcome, of course. And this is open to any subject, no matter how obscure you think it might be – if it has a reference well-known in those circles, let’s hear it.
(I’m sure this has been done before, but all my searches crashed out today.)
I’ll give a few examples I can think of for now:
The C Programming Language, Brian Kernighan & Dennis Ritchie
a.k.a “Kernighan & Ritchie” or “K & R”.
Not just the best book on C, but the best computer programming book ever. Slimmer and shorter than most computer programming books, but tells you exactly what you need to do it right. By two of the people who wrote the language itself.
The Sunset Western Garden Book, Sunset Magazine
For the region west of the Continental Divide in the lower 48, and California especially, covers the basics of gardening and a detailed guide to each plant species.
Mountaineering: Freedom of the Hills, Don Graydon (& Kurt Hanson), ed.
a.k.a. “Freedom of the Hills”, “FOTH”
A collection of contributions from specialists in each field, this is a complete guidebook for all aspects of mountaing climbing, covering equipment, techniques, and safety on rock, ice, and snow.
