The importance of the work of Alan Turing is well known to everybody. The most complete resources on Turing’s work are The Turing Digital Archive, the book “The essential Turing” of Jack Copeland and the volumes of his “Collected works”. The problem with the Digital Archive is that it contains scans of manuscripts from which is not so easy to read, yet I think it is very interesting to browse.

Below,
I list most of Turing’s papers and some links for them. The links are freely accessible
and they lead to easily read pdf files that are scans or reprints of the original
publications or at least they are very close to it.

The
links are listed as found on the web; any possible copyright issues or broken
link issues should regard the owners of the sites that host the linked files. In case you have any suggestions for the list please add a comment.

At the end you may find something that should be an anecdote but it is a real problem in academic publications.

One of this papers is Turing's most famous paper.
