Take a brief tour of the Library Discovery Service (LDS) at the video below. The LDS combines the search power of most databases and the library catalogue into one interface and allows you to do comprehensive literature reviews across multiple sources instead of searching databases individually.
If you want to search chemistry and science databases individually, please take a look at the Mathematics Databases links BELOW.
To search general reference databases individually please see the links BELOW.
MathSciNet covers mathematical literature since 1940 this international database provides bibliographic data and reviews of mathematical research literature from 1700 current journals, books and other original documents.
Arxiv.org is a highly-automated electronic archive and distribution server for research articles. Covered areas include physics, mathematics, computer science, nonlinear sciences, quantitative biology, quantitative finance, statistics, electrical engineering and systems science, and economics. arXiv is maintained and operated by the Cornell University Library with guidance from the arXiv Scientific Advisory Board and the arXiv Member Advisory Board, and with the help of numerous subject moderators.
Wolfram Math World is a free database with extensive citations to books and journal articles, including some in full-text , thousands of downloadable Mathematica notebooks; several types of interactive entries, including LiveGraphics3D applets for interactive three-dimensional geometry and a powerful full-text search engine with both basic and advanced searching capabilities.
