STN Database Summary Sheet
The LCA File is a training database for learning how to use the CA File. It is a static file that contains references from eight weekly issues of Chemical Abstracts (CA), two each from 1969, 1974, 1979, and 1984 (representing the 8th, 9th, 10th, and 11th Collective Index periods), as well as references from LCASREACT (1987-1988). The LCA records contain bibliographic information, in-depth substance and subject indexing, and abstracts, which are available for most citations.
Left truncation may be used in the Basic Index only.
LCA is a member of the following file cluster: LEARNING.

EXPAND may not be used with super search fields. Use EXPAND with the individual field codes instead. (2) Either STN format or Derwent format may be used.
Hit-term highlighting is available in all fields. Highlighting must be on during SEARCH in order to use the HIT, HITIND, HITRN, HITSTR, KWIC, and OCC display formats.
