he contents of the 1958-1959 Current List of Medical Literature (CLML) were added to OLDMEDLINE in July 2000. The OLDMEDLINE file now contains 991,869 citations with the addition of these 220,582 citations from the 1958-1959 publication. Of these newly added citations, 106,775 are from the 1959 CLML and 113,807 are from the 1958 CLML. OLDMEDLINE was first made available in December 1996, with over 307,000 citations originally published in the 1964 and 1965 Cumulated Index Medicus (CIM) (see NLM Technical Bulletin 1996 Nov-Dec; (293): 1, 4-6). In November 1998, the library added to OLDMEDLINE over 400,000 citations published in the 1960 through 1963 CIM (see NLM Technical Bulletin 1999 Jan-Feb; (306): e4).
OLDMEDLINE is available free to searchers on the Web via Internet Grateful Med and will be accessible from the NLM Gateway when it becomes available (currently expected in the Fall of 2000).
The newly added records also contain periods in the Title Abbreviation (TA) data element because the 1958-1959 CLML included periods.
