CSA Materials Research Database with METADEX covers publications related to materials science, metals, alloys, ceramics, polymers, and engineering composites. Topics covered include raw materials, processing, refining, end uses, performance, and recycling, as well as business aspects of materials science. Databases begin in the 1960s, 1970s or 1980s; select older references are included. Updates are monthly, with about 100,000-125,000 records added annually. Records are bibliographic, including indexing and abstracts (if available), but not full text online.
MEDLINE on this service contains over 4 million citations and abstracts, providing unparalleled access to worldwide biomedical literature. The database contains a broad range of medical topics relating to research, clinical practice, administration, policy issues, and health care services. Produced by the U.S. National Library of Medicine, MEDLINE contains all records published in Index Medicus and since 2002, most citations previously included in separate NLM specialty databases such as SPACELINE and HISTLINE.
