Mathematical Reviews is an indexing service provided by the American Mathematical Society, giving the publication data of mathematics publications which are most often (but not always) accompanied with a short or a featured review “article” or with the original abstract. Its online version is called MathSciNet:
It requires subscription, but some of its services, most notably the so called Relay Station does not. Relay Station gives the full reference (and sometimes a link to the journal) called by the MR number of the review, but does not provide the abstract or the review unless one has a subscription.
MR numbers have two formats. Relay station accepts both formats. To link from lab, the URL is of the following form:
where FORMAT includes the code after the MR. So MR92a:81191 has
and MR1289330 has the URL
MR numbers can be discovered using the free MR Lookup service:
This can also provide citations in BibTeX format. The MRef tool can also be used to parse citations copied and pasted from elsewhere.
A short redirect to this page is MR (i.e. [[MR]]).
