The
NASA Scope and Subject Category Guide is a ready-reference
tool to assist authors, indexers, and information
managers in the high-level subject classification
of technical aerospace materials. In addition,
the guide can serve as an aid to searching in
databases that use the NASA category scheme,
for example, the NASA Aeronautics and Space Database and the NASA Technical Reports Server.
Finally, for those information managers tasked
with compiling collections of aerospace materials,
this resource can be used as a guide in the selection
of appropriate materials.
The
guide comprises a 2-level subject classification
scheme consisting of 10 broad subject divisions
further divided into 76 specific subject categories.
The scope of the scheme is comprehensive in that
it covers not only areas of aerospace technology
and the natural space sciences, but also supporting
areas of engineering, physics, chemistry, and the
Earth and life sciences. A more specific treatment
is given to those areas that are most pertinent
to aerospace research.
The
display for each subject category provides: (1)
the category name and corresponding number,
(2) a description of the scope of the category including
cross references, and (3) a general indication
of the relevance of certain topics to NASA activities
and aerospace research in general. In addition,
each category display includes a listing of ‘Input
Subjects of Specific Interest.’ In all, there
are nearly 3,000 input subjects, which
are presented as a browsable index to further support
the identification
of appropriate subject categories.
