MEDLINE records will now be included as part of the regular daily updates for EMBASE. The unique MEDLINE records retrieved from EMBASE differ from their counterparts in MEDLINE by having EMTREE indexing.
To accommodate the new MEDLINE records, several new features have been added to EMBASE:
-
New Copyright MEDLINE (CP) field indicates that the record came from MEDLINE. This field is part of the BIB (default) display format.
-
New File Segment (FS) Data The term MEDLINE appears in the /FS field when the record is a unique MEDLINE record. This field is both searchable and displayable.
-
New values for SET RANGE Enter SET RANGE=MEDL to restrict retrieval to unique MEDLINE records only. Enter SET RANGE=NMED to restrict retrieval to traditional EMBASE items only
-
New update fields The Update Date MEDLINE (/UPAL) and Entry Date MEDLINE (/EDAL) allow customer current-awareness alerts (SDIs) to retrieve both traditional EMBASE records and unique MEDLINE records.
Please note the impact on your EMBASE SDI search strategies:
-
Including the Update Date (/UP) or Entry Date (/ED) fields in your EMBASE SDI search strategy will now restrict your retrieval to traditional EMBASE records only.
-
If you want to include MEDLINE unique records in your SDI, you must update your search strategies with the new /UPAL and /EDAL field.
-
If you take no action, your SDIs will run as always with no unique MEDLINE data included.
MEDLINE Coverage is Extended back to 1947
The MEDLINE backfile has been extended back to 1947, adding an extra 63,839 records to MEDLINE's coverage.
These records are not eligible for current-awareness alerts (SDIs).
