zbMATH Open (formerly known as Zentralblatt MATH) is the world's most comprehensive and longest-running abstracting and reviewing service in pure and applied mathematics. It is edited by the European Mathematical Society (EMS), the Heidelberg Academy of Sciences and Humanities, and FIZ Karlsruhe.
1991-present. An e-print service which presents papers in physics and related disciplines, mathematics, nonlinear science, computer science, and quantitative biology.
A full-text collection of over 3,400 major scholarly journals and over 100,000 scholarly monographs. The digitized archive includes the first issue published for each journal (some are from 1665 to the present); but excludes the most recent 2 to 5 years for most journals.
An excellent starting point for research across a broad stretch of academic subjects with thousands of full-text journals and abstracted and indexed journals. This database is sourced with PDF images for the great majority of journals; many of these PDFs are native (searchable) or scanned-in-color.
Online search engine that indexes articles, theses, books, abstracts, conference proceedings and court opinions; from academic publishers, professional societies, online repositories, universities and other web sites. Although this is a large index, once you have located a citation, you may have to access the complete article using library databases.
A 48-page in-depth report that looks at the way mathematical sciences are used in industry today, along with assessing the skills, training and curriculum that will best prepare graduates for future mathematical careers.
