The SOA/NASA Astrophysics Data System (ADS) is a digital library portal for researchers in astronomy and physics operated by the Smithsonian Atrophysical Observatory (SAO). It maintains three databases which cover publications in astronomy and astrophysics, physics, and the arXiv e-prints.
The ADS contains mostly bibliographic records and abstracts with some full-text available for older literature.
INSPIRE is a trusted community hub that helps researchers to share and find accurate scholarly information in high energy physics (HEP). It serves as a one-stop information platform that provides users with high-quality, curated content covering the entire corpus of HEP literature, conferences, institutions, journals, researchers, experiments, jobs, and data.
IoPScience is an online service for journal content published by the Institute of Physics Publishing.
A number of short tutorials have been designed to help you search the database.
Physical Review Online Archive, or PROLA, provides access to Physical Review Series I and II (1893-1969), Physical Review A - D (1970-2019), Physical Review E (1993-2019), Physical Review Letters (1958-2019), and Reviews of Modern Physics (1929-2019). At the end of each calendar year, PROLA adds another year of content.
Web of Science (WoS) indexes leading scholarly journals, books, proceedings, and other formats. Its major subject areas include the natural and social sciences and arts and humanities, with coverage for all areas back to 1900. The heart of WoS is the "Core Collection," which contains records of articles from the highest impact journals worldwide—including open access journals.
These video tutorials teach aspects of searching, analyzing results, creating a researcher profile, and more.
