MathSciNet This link opens in a new windowAn electronic publication offering access to a carefully maintained and easily searchable database of reviews, abstracts and bibliographic information for much of the mathematical sciences literature. Continuing in the tradition of the paper publication, Mathematical Reviews (MR), which was first published in 1940, expert reviewers are selected by a staff of professional mathematicians to write reviews of the current published literature; over 40,000 reviews are added to the database each year. Extending the MR tradition, MathSciNet contains over 2 million items and over 1 million direct links to original articles. Bibliographic data from retrodigitized articles dates back to the early 1800s. This web of citations allows users to track the history and influence of research publications in the mathematical sciences.
