revision was published in 1978 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, for increasing n. The most widely implemented standard is [The
-Revised^5 Report on Scheme](http://docs.racket-lang.org/r5rs/index.html),

+Revised^5 Report on Scheme](http://www.schemers.org/Documents/Standards/R5RS/HTML/),
or R5RS, published in 1998.

-A new standard [R6RS](http://docs.racket-lang.org/r6rs/index.html) was ratified
+A new standard [R6RS](http://www.r6rs.org/final/html/r6rs/r6rs.html) was ratified
in 2007, but this has many detractors and has not been fully accepted in the
-community.
