Despite its name, the front page of Readscheme.org is not specific to
Scheme. Linking to the Wayback Machine copy gives curious visitors an
opportunity browse it anyway.
This is a mirror of library.readscheme.org. The domain readscheme.org
included a bunch of other stuff only tangentially related to Scheme.
Since that stuff is off-topic at scheme.org and readscheme.org has
been taken over by a domain squatter, the least confusing thing to do
is probably to disable the link.
There are many versions of index.html newer than the bibliography
pages. Take the latest copy of index.html from 2012.
