MR4000000

Today, item number MR4000000 was added to MathSciNet. Hurray!  It is a paper on a local Jacquet-Langlands correspondence by Vincent Sécherre and Shaun Stevens, published in Compositio Mathematica. 

It will take a while (a few months) for us to send the paper to a reviewer, for the reviewer to write something about the paper, and for us to post the review to MathSciNet.  So, to start, we have the bibliographic information in place:

In the old days, when there was only the paper Mathematical Reviews, nothing was “added” until we had the review in hand and could print it as part of one of the big orange volumes that some of us remember.  Here is a photo of Robert Bartle hand stamping the item that became MR1000000.  Everyone came out to help.  Clearly this is a nice day, and not late February in Michigan.  (The review was published in February 1990.)

For comparison, here are dates of other million milestones, and the gaps between them

MR0000001: January 1, 1940
MR1000000: February 22, 1990 — 50 years, 1 month, 21 days [18,316 days]
MR2000000: January 30, 2004 — 13 years, 11 months, 8 days [5,090 days]
MR3000000: November 06, 2013 — 9 years, 9 months, 8 days [3,569 days]
MR4000000: September 19, 2019 — 5 years, 10 months, 14 days [2,144 days]

At this rate, we could hit MR5000000 in about 3 years!

We had a little party to celebrate.  Here is our cake:

Here is a panoramic photo of us getting ready to eat the cake.

This is a great opportunity to thank the people who made this possible.  First of all, there are the great people who work for the AMS at the Mathematical Reviews offices in Ann Arbor, MI.  We have a lot of talented people here!  Then we have the publishers, whose cooperation makes it feasible to create a database of the research literature in the mathematical sciences.  Finally, there are the 20,000+ reviewers, who enrich the database with their  comments and insights, making MathSciNet a very valuable tool for mathematical researchers.  Thank you all!
