520 Walker (SUNY-Albany) and Janes (Univ. of Michigan) have
sensibly chosen one widely used online retrieval system,
DIALOG, to illustrate their discussion of the principles
and techniques of online searching. The reader who closely
examines the numerous reproductions of DIALOG printouts
will have a strong conceptual foundation on which to build
real searching experience. The only obvious limitation is,
of course, that not all searchers use DIALOG, but the
authors have largely done a good job of generalizing their
lessons. The major portion of Online Retrieval consists of
a comprehensive treatment of hands-on searching techniques
with attention given to Boolean logic, controlled
vocabulary and free-text searching, display formats, and
ways to minimize expense of time and money. Additional
topics include the reference interview, evaluation of
search results, and establishing and managing an
institutional search service. One chapter briefly
describes Internet. A few oversights slightly weaken the
value of the text, e.g., typographical errors in the
DIALOG examples might confuse readers, and references to
DIALOG bluesheets occur prior to Chapter 10 where they are
more fully described. Overall, however, this book is
recommended, particularly to students who would benefit
additionally from an experienced instructor's elaboration
and clarification of the text.
