The arXiv (pronounced "archive") is a repository of electronic preprints, known as e-prints, of scientific papers in the fields of mathematics, physics, astronomy, computer science, quantitative biology, statistics, and quantitative finance, which can be accessed online.
IEEE Xplore, produced by the Institute of Electrical and Electronics Engineers, provides full-text access to IEEE transactions, journals, magazines and conference proceedings published since 1884, and all current IEEE Standards.
contains citations for nearly 800 core English-language, scientific and technical publications back to 1983. Content includes coverage of a wide variety of applied science specialties—acoustics to aeronautics, neural networks to nuclear and civil engineering, computers and informatics and more.
Tips for searches & keywords
When searching for content related to physics, use synonyms/similar terms separated by OR, then use AND to combine with other keywords. Example: (refraction OR deflection OR refractivity) AND sound
Consider synonyms and related keywords when searching. E.g.: acceptor OR hole
Use quotation marks to indicate searching for a phrase, not separate words E.g. "uncertainty principle"
