Legal NoticesNational Library of Medicine / MEDLINE notice:
Unless otherwise prohibited, organizations or institutions may download small amounts of NLM-produced citations for redistribution. For MEDLINE, this is about 1,000 per month or 12,000 records for each year of coverage. For other MEDLARS databases, it is approximately 25% of the records in the file except for AIDSLINEŽ, AIDSTRIALS, and AIDSDRUGS which may be downloaded in their entirety. Since NLM makes corrections and enhancements to and performs maintenance on these records at least annually, you should plan to replace or correct the records once a year to ensure that they are still correct and searchable as a group.
NLM databases are produced by a U.S. government agency and as such the contents are not covered by copyright domestically. They may be copyrighted outside the U.S. Some NLM produced data is from copyrighted publications of the respective copyright claimants. Users of the NLM databases are solely responsible for compliance with any copyright restrictions and are referred to the publication data appearing in the bibliographic citations, as well as to the copyright notices appearing in the original publications, all of which are incorporated by reference. Users should consult legal counsel before using NLM-produced records to be certain that their plans are in compliance with appropriate laws.
All records must be identified as being derived from NLM databases.
