NASA-funded project whose main resource is an Abstract Service, which includes three sets of abstracts: 1) astronomy and astrophysics, containing approximately 330,000 abstracts; 2) instrumentation, containing approximately 460,000 abstracts; and 3) physics and geophysics, containing approximately 220,000 abstracts. In addition to the Abstract Service, the ADS provides pointers to astronomical data catalogs and data archives, making data collected by NASA space missions available. Direct access to ADS (no UT EID required) is also available.

Created by Paul Ginsparg at the Los Alamos National Laboratory, Los Alamos, New Mexico and launched in 1991, arXiv.org (formerly xxx.lanl.gov) is a fully automated electronic archive and distribution server for research papers. Areas covered include physics and related disciplines, mathematics, nonlinear sciences, computational linguistics, and neuroscience.
Web portal for easy public access to the peer-reviewed papers resulting from NASA-funded research held in PubMed Central (PMC). PMC is a full-text, online archive of journal literature operated by the National Library of Medicine.
Updated weekly. Indexes the research literature of physics; electrical engineering and electronics; & computers and control. Offers over 15 million records and strong international coverage. The archive portion, which was formerly separate, is now integrated with the current file.
Updated weekly. Covers more than 12,000 journals in all subject areas. Also includes citations to conference proceedings. Choose Search in order to search the database by topic, author journal or address. This search includes articles, reports, books and book reviews and may be searched by keyword (topic searching), author (person searching), institution, or geographical area. Choose Cited Reference Search to search for articles that cite an author or work. This search includes the list of references at the end of articles and will allow you to search by the cited author, cited work, cited year or a combination of the three. Choose Advanced Search to combine aspects of the other two searches. The default selection for searching is for all the citation databases and for all years of coverage; both selections can be changed from the main search screen at the time that you select your search.
