RECOMMENDED databases have some direct appeal for those searching for information in Physics & Astronomy. The listing below includes indexes, collections of literature by publisher or repository, and finally reference tools. Web of Science (a citation database that tracks the evolution of research in a given field), MathSciNet (focus on mathematics), and SciFinder (focus on chemistry) are all indexes. IOP, PROLA, AIP, IEEE/IET, arXiv, SCOAP3, ScienceDirect, Wiley, ADS, and HEP are publisher specific databases or subject specific repositories. Reference tools include AccessScience (a e-form of McGraw Hill Encyclopedia of Science and Technology), the CRC Handbook and eMagRes (the e-form of the Encyclopedia of Nuclear Magnetic Resonance). RELATED databases, on the other hand are less-directly relevant.
