What is your most referred to piece of documentation?

Question

For me it's got to be the Microsoft SQL Server Cast and Convert reference. I must love that page, I seem to visit it several times a day.

Answer 1

PHP Documentation for me - clear, concise, user tips (although these are not always correct and secure - pinch of salt etc). Also good for typing directly into an address bar if you know the function name, eg php.net/in_array - straight to the function's page.

Answer 2

The YUI documentation has had a good number of views over my last few projects...a good example of a clear and concise API

Answer 3

Definitely should be http://www.w3.org/TR/xslt :)

Answer 4

It depends a lot on what I'm doing and what my toolset is. In generaly these days it is probably Stroustrup's The C++ Programming Language.

Answer 5

From time to time, I still find that people need my services maintaining/fixing/adding new features to ASP site (VBScript) pages from time to time (yuck). The MSDN VBScript reference is usually all I need.
