Jahrbuch über die Fortschritte der Mathematik [1868-1930]

ZentralBlatt MATH [Limit of three results to non-subscribers]

The Zentralblatt MATH Database contains more than 2.0 million entries drawn from more than 2300 serials and journals and covers the period from 1868 - present by the recent integration of the Jahrbuch database (JFM). The entries are classified according to the Mathematics Subject Classification Scheme (MSC 2000).

1. Alpha version of Euler Service

The EULER service provides a one-stop-shop in your search for mathematical resources such as books, pre-prints, web-pages, abstracts, proceedings, serials, technical reports and thesis. Through our single search interface you can query a range of databases simultaneously - one search for you, many searches for the system.
2. AMS World Math Preprint Archive

The mission of the Directory of Preprint and e-Print Servers is to make available to the mathematical community the current homepage URLs and email contacts of all mathematical preprint and e-print servers throughout the world.

5. Distributed Digital Library of Mathematical Monographs Collection

The Distributed Digital Library of Mathematical Monographs is comprised of full-text monograph collections at three institutions: Cornell University Library, The University of Michigan Library, and the State and University Library Göttingen (forthcoming).

The Cornell University Library Historical Mathematics Monographs is a collection of selected monographs with expired copyrights chosen from the mathematics field. These were monographs that were brittle and decaying and in need of rescue. These monographs were digitally scanned and facsimile editions on acid free paper were created.
6. Eric Weisstein's World of Mathematics

MathWorld is a comprehensive and interactive mathematics encyclopedia intended for students, educators, math enthusiasts, and researchers. Like the vibrant and constantly evolving discipline of mathematics, this site is continuously updated to include new material and incorporate new discoveries.

7. Mathematical Atlas

A collection of short articles designed to provide an introduction to the areas of modern mathematics and pointers to further information, as well as answers to some common, and some not so common, questions. The material is arranged in a hierarchy of disciplines, each with its own index page.
8. Mathematics Subject Classification Scheme, 2000

The current classification system, 2000 Mathematics Subject Classification (MSC2000), is a revision of the 1991 Mathematics Subject Classification, which is the classification that has been used by Mathematical reviews (MR) and Zentralblatt Math (Zbl) since the beginning of 1991. MSC2000 is the result of a collaborative effort by the editors of MR and Zbl to update the classification.
9. Scientific Graphics Project

The Scientific Graphics Project is concerned primarily with surfaces in R3 (three dimensional euclidean space). The surfaces are organized into three major categories: Minimal Surfaces, CMC (Constant Mean Curvature) Surfaces, and Level Surfaces.
