| We have previously recommended searching the HCLL catalog by keywords to best locate a variety of
materials (see
article from January-February 2005). Keywords searching is most similar to “googling,” a search we all know well.
If you know the title you want to see, use the Titles index; you will not find
Current Legal Forms or Dunnell Minnesota Digest as searches in the Subject Headings index.
But searching the catalog by Subject Heading can also be useful if you understand its uses, do it well, and really look at your results.
Subject Headings are a controlled vocabulary, developed by the Library of Congress, and
include cross-references to and from related topics. The Library of Congress subject heading system also provides references from common alternative terms to the controlled terms that LC has selected to describe the topic.
We use LC headings at HCLL. One or more subject headings are assigned to every book in the collection.
The heading, often with a geographic subdivision, is what the book is most generally “about.”
It is important to remember that subject headings do not represent the index of the book.
The “Keywords” search in our catalog is a closer relative of the book index.
But more often, you need to look at the index of a book on “your” general topic to do a more specific search.
Reference librarians are happy to check indices for you (call
612-348-2903).
Since a subject heading is a controlled vocabulary, it is best to be general when searching the HCLL subject catalog.
We do provide those cross-references to related or narrower topics, so a general search will offer narrower specifics if they are available.
A subject heading search for LABOR LAWS AND
LEGISLATION [click links to view results of the search], in addition to retrieving general treatises on that subject, will also retrieve a
long list of narrower LC subject headings which we have assigned to more focused
treatises. Among the narrower headings are EMPLOYEE ASSISTANCE
PROGRAMS, LAYOFF
SYSTEMS, and SICK
LEAVE.
Since subject headings represent a controlled vocabulary, it is also important to remember that the language is a bit more formal than spoken or Google language. Use
MOTOR VEHICLES or
AUTOMOBILES, instead of
CARS.
It is, of course, also important that you spell the heading correctly!
The HCLL catalog is, however, very forgiving. You will be dropped into a list of valid LC headings whatever you enter.
Look around! If you have entered a misspelling, you should be very near
the correctly-spelled term. If you have guessed incorrectly as to the controlled language, your entry of
CONSTRUCTION LAW should be very close to
CONSTRUCTION INDUSTRY and to
CONSTRUCTION
CONTRACTS. If you have been unsuccessful guessing about the controlled vocabulary, the HCLL catalog always gives you the option of converting a completely unsuccessful subject-heading search into a keywords search.
DECEPTIVE TRADE PRACTICES does not work as a subject heading, but
clicking and re-running it as a Words search results in several titles.
Then it is a simple matter of looking at the full bibliographic record for one or more of them, viewing the subject headings we have assigned to them, and clicking on one of the headings to retrieve other titles on that subject.
The HCLL catalog is also convenient because it is searchable by those geographic subdivisions as well as by the main subject headings.
So, if you have a client with a problem in Wisconsin, just do a subject-heading search for
WISCONSIN, and you will retrieve a list of topics for which we own books on Wisconsin law.
If you have questions about searching subjects in the HCLL catalog, call a Reference Librarian.
We are happy to help on this or any other question.
