This subject category lists recommended databases covering engineering and the physical sciences: chemistry, geosciences, mathematics, physics, and statistics. Many provide full-text sources, otherwise use the citations they provide to request copies via your local library's interlibrary loan service.
The Civil Engineering Database (CEDB) indexes citations for all ASCE publications. The database covers all the journals, conference proceedings, books, standards, manuals, magazines, and newspapers published by ASCE. Journal papers with abstracts go back to 1970. Non-abstract journal records go back to 1958. The book records are complete dating back to the early 1900s.
Search or browse full text and citations to articles, conference proceedings, reports, data catalogs, dissertations, and digitized books in astronomy and astrophysics. Includes scans of historical astronomical publications. 1800s-present.
Searches the NLM ChemIDplus database of over 370,000 chemicals and displays numerous properties (and sometimes lists citations for sources of the data, but it does not search article citations directly). Allows various search capabilities beyond the Lite version including chemical structure, toxicity, and physical property searching. You will need a web browser that has a recent version of Java installed. There is a structure drawing and display applet named Marvin. An alternative method to provide the capabilities needed to accept a structure query is the Chime plug-in.
NTRS indexes citations, full-text documents, and multimedia content from NACA and NASA publications and research reports. Content includes conference papers, journal articles, meeting papers, patents, research reports, theses and dissertations, images, movies, and technical videos. Full text available as PDFs. 1903-present.
TranStats indexes statistical data on all forms of transportation from agencies in USDOT. Much of the data can be downloaded in spreadsheet or statistical software formats. 1990-present.
TRID indexes citations, abstracts, and some full text of journal articles, books, conference proceedings, technical reports, environmental impact statements, and theses on transportation research. It integrates the former TRIS and ITRD databases.
