Complete (possibly official) list of "What is..." articles from the Notices of the AMS

Assuming you have access to MathSciNet, a search for Title containing "What is" and Journal containing "Notices" seems to work pretty well.

I wrote to Allyn Jackson, who is in charge of this feature. I reproduce her response below with her permission.

I can indeed answer this, and unfortunately the answer is no. Embarassingly, we don't have an online index for the WHAT IS column. The Notices web site is rather primitive, and there is no natural place to put such a list. We are hoping to do an upgrade soon, and this would include a WHAT IS index.

I knew about the list of WHAT IS columns at Cornell, but I didn't know about the other one at arminstraub.com. I have my own list that I use in editing the column, and, like arminstraub, I have column #106 as Heil's "What is a frame?" So it seems to me that the arminstraub list is complete, but I did not check every title against my own list. The last column in my list is #110, so arminstraub is missing the 4 latest columns.

It is gratifying to know that there are some serious WHAT IS fans out there. Comments and suggestions are welcome and can be sent to [email protected].

It seems they made a list in the meantime:
