Describes parts of the Racket language that go beyond the learning-oriented fragments of HtDP. * [Racket Reference](http://docs.racket-lang.org/reference/index.html) defines the core Racket language and its most prominent libraries. Less friendly than Racket Guide, but more precise and complete. *

The first standard was published in 1975. A revision was published a few years later called "The revised report on Scheme, a dialect of Lisp." Thereafter, revisions of the standard were titled "The Revised Revised Report..." and so on, or "The Revised^n Report..." for short. One widely implemented standard is [The Revised^5 Report on Scheme](http://www.schemers.org/Documents/Standards/R5RS/HTML/), or R5RS, published in 1998. Another standard [R6RS](http://www.r6rs.org/final/html/r6rs/r6rs.html) ([libraries](http://www.r6rs.org/final/html/r6rs-lib/r6rs-lib.html)) was ratified in 2007, but had many detractors and wasn't fully accepted in the community. Currently Scheme is being split into a lean minimal base, now ratified as [R7RS-small](http://trac.sacrideo.us/wg/raw-attachment/wiki/WikiStart/r7rs.pdf) ([errata](http://trac.sacrideo.us/wg/wiki/R7RSSmallErrata)), and a richer language [R7RS-large](http://www.scheme-reports.org/2015/working-group-2.html) (still being designed) that standardizes many add-ons. * [Scheme FAQ](http://community.schemewiki.org/?scheme-faq) * [Scheme Requests for Implementation](http://srfi.schemers.org/) (SRFIs) * [The Scheme Programming Language](http://scheme.com/tspl4/)/4ed, by R.
