Places where you can find Guile stuff.

Lumpy Guile

is a collection of Guile-centric code, documents and other stuff [see also: nepotism].

Please let us know if you have other resources that should be listed here.

General resources for the Scheme programming language.

The Revised⁶ Report on the Algorithmic Language Scheme

is the forthcoming Scheme standard, currently being standardized. Guile does not implement it (yet).

The Revised⁵ Report on the Algorithmic Language Scheme

is the current Scheme standard. Guile isn't totally compliant.

The Revised⁴ Report on the Algorithmic Language Scheme

is the previous standard.

The Scheme Repository

is a good source of links, code, and documentation for scheme.

Schemers.org

is more of the same.

Scheme home page

at MIT. Not quite as extensive as the Scheme Repository or Schemers.org

The Scheme Request For Implementation site

contains proposals for a number of Scheme extensions. Many of these tend to exist in one form or the other in a lot of the different Schemes, but can have wildly different interfaces. The SRFI process is essentially aimed at making these non-standard features more standard, without actually being standard [see also: obfuscated]. Guile 1.8 implements a large number of SRFIs.

Greg Badros' Scheme Lecture Notes

are, as the title implies, a set of slides that touch on a variety of subjects related to scheme programing, including samples of similar code written in C and scheme, lambda calculus, and lists.
