HISTLINE Update

N/A

March 1997 [posted]

A restructured HISTLINE was available online in 1994, replacing an earlier version created in 1978. When the new MeSH-based HISTLINE was created (see pages 1,9-14 of the July-August 1994 Technical Bulletin), approximately 30,000 citations could not be transferred from the old database because they lacked MeSH Headings.

NLM committed to a three-phase project that would add MeSH Headings to these citations and then reintroduce them to the HISTLINE database. Phase I of this retrospective conversion was completed in two updates. In June 1996, 14,974 citations to journals in the NLM collection but not covered in any other NLM database, were added to HISTLINE at that time (see page 2 of the July-August 1996 Technical Bulletin). In December 1996, an additional 1,848 records were added.

In Phase II, 9,210 citations, to journal articles from non-NLM sources, were converted. These citations were added to HISTLINE in January 1997. These records can be searched in HISTLINE as follows:

USER:
HMDOLD (SI) AND 9701 (EM)

Both MeSH Headings (MH) and Keywords (KW) may be used for subject searching. Abstracts are not available online for these citations.

In Phase III, NLM will convert old HISTLINE citations to other non-NLM sources, including book chapters, and papers from conferences and meetings. These citations are expected to be added to HISTLINE later in 1997.
