I have noticed that Mathematical Atlas website, which was maintained by Dave Rusin, no longer exists. (I am not sure how long ago this happened. The dates in the following paragraph suggest some time in 2015.) This site is referenced in some posts on this site and probably in many comments. You can find a lot of websites, notes, papers, books referencing this site. These facts suggest that it was a valuable resource with wealth of interesting information,

In the Wayback Machine this is the most recent working version of Dave Rusin's homepage I was able to find.1 This is the last snapshot of working welcome page to Mathematical Atlas I found there.

I am sure that most (or maybe all) of the contents of this site can be find using Wayback Machine (a.k.a. Internet Archive). But still I want to ask:

  • Is a complete mirror of this website available somewhere online?
  • Has the website moved and is it now hosted on another host? (This seems unlikely to me, since if this was the case, I would expect some kind of information or at least a link at the old page.)

1EDIT: I did not notice that at the time of posting the question, but the last working snapshot of Dave Rusin's website is linking to http://www.math-atlas.org/welcome.html rather than http://www.math.niu.edu/~rusin/known-math/ It seems that this new site has already been up in 2015 and according to the answer posted to this question, there are plans to revive it.


The current content of http://www.math-atlas.org/ is this message:

The Mathematical Atlas will re-appear at this space some time in 2016. (It was taken off line when its former hosts at Northern Illinois University math department migrated to a university-wide computer network.) Please contact Dave Rusin (rusin@math.utexas.edu) for more details.

    $\begingroup$ I probably should have figured this myself. (It is the first hit in Google when searching for mathematical atlas.) But I guess it might be still useful that I asked this. It might help to get this information to other users of this site - and I personally consider it to be a useful information. $\endgroup$ – Martin Sleziak May 29 '16 at 10:04
  • $\begingroup$ For what it's worth, it was the second link for me. ;) $\endgroup$ – Travis May 29 '16 at 10:34

    $\begingroup$ 2016 has come and gone, and the same message is there. $\endgroup$ – Gerry Myerson Aug 29 '17 at 6:15

    $\begingroup$ @GerryMyerson it's also true in the later part of 2018... $\endgroup$ – KCd Sep 29 '18 at 12:26
