- OLDMEDLINE available in PubMed, effective September 30, 2003; previously in the NLM Gateway.
- HSRProj available in the new NLM Gateway, effective December 1, 2011, and at http://wwwcf.nlm.nih.gov/hsr_project/home_proj.cfm.
- TOXLINE® and ChemID® are available at http://sis.nlm.nih.gov/. The TOXNET TOXLINE includes citations to bibliographic and other report-like data from special collections and closed subfiles. The standard journal citations in toxicology that make up TOXLINE Core are available as part of MEDLINE/PubMed.
- PubMed has a Toxicology Subset available.
- NLM broadened its coverage of toxicology by indexing about 40 more MEDLINE journals previously in TOXLINE.
- CATLINE and AVLINE were converted to LocatorPlus in February 1999.
1NLM ceased updating these databases at the end of 2000 but they remained available to the public via Internet Grateful Med (IGM) until it was retired in 2001.
2Number of unique monographic records, including book chapters, added to LocatorPlus; and the date records were added from the former NLM database. As of May 1, 2000, the collaborating data producers (i.e., NASA, ECRI, HMD, and KIE) created new monographic records for LocatorPlus; NASA agreement ceased late 2005; KIE agreement ceased January 2007.
3Number of unique journal records added to MEDLINE/PubMed and the date the records were added from the former NLM database. For AIDSLINE, includes unique newsletter citations.
4Percentage of former, separate database that consisted of citations originally from MEDLINE; date subject subset available in PubMed.
5NLM continued to add selected meeting abstracts on AIDS/HIV (ceased with 2010 International Conference on AIDS added January 2012), health services (ceased with 2010 Academy Health Meeting added in January 2012), and space life sciences (ceased late 2005) to the NLM Gateway.
6In June 2002, 30,933 monographic and audiovisual records in LocatorPlus that had previously resided in the legacy ELHILL databases BIOETHICSLINE, HISTLINE, and SPACELINE were updated. Please see the Jul-Aug 2002 NLM Technical Bulletin article Migration of Monographic Citations to LocatorPlus: Merge Project for details.
7Approximately 26,300 bioethics-related MEDLINE journal citations were also revised by NLM to add some of the special fields of former BIOETHICSLINE records including keywords and other abstracts. NLM revised other MEDLINE journal citations to add some of the special fields of the former SPACELINE and POPLINE databases.
8HSTAR was formed by the merger of HEALTH (1978-1995) and HealthSTAR (1994-1995).
9Watch the National Information Center on Health Services Research and Health Care Technology (NICHSR) homepage at http://www.nlm.nih.gov/nichsr/nichsr.html for future announcements of subject strategies.
10POPLINE meeting abstracts were not converted to the NLM Gateway because there were fewer than 1,200 and they all had a publication date prior to 1989.
11Johns Hopkins University Center for Communication Programs and NLM ceased the POPLINE Agreement. See the References below for more details.
