Finding
Books
Catalogs
provide information about materials contained in a single collection,
library, or group of libraries. They can be in book, card, or electronic
(online) form. The collections of the Yale University Library are currently
represented in multiple online catalogs.
Orbis,
Morris (the Law Library catalog) and the Center for Research Libraries
(CRL) catalog constitute the Yale University Library online catalogs.
Orbis
includes records for books, serials (journals, newspapers, magazines),
manuscript materials, audio-visual materials, musical scores, maps, government
documents, and databases. It does not include records for articles.
ORBIS
There are four major ways to search Orbis: by title, by author, by keyword,
and by subject heading. Title and author searches are the most straightforward
-- you're looking for a specific book or books, and you know the title
or the author. When searching by title remember to omit the initial article
(the, a, an) of any language (le, la,
el, der, die, das, and so on): catcher
in the rye. When searching by author remember to type the last name
first: faulkner william.
Author
Search.
Type rodriguez richard in the search box, then choose Author.
The result is an index screen, listing results of our search: three titles
by Richard Rodriguez, and one by another person named Richard Rodriguez
who was born in 1962. Click on 1. This is a typical book record in Orbis,
with fields for author, title, publication information, description (i.e.,
length, size, whether there are illustrations or a bibliography), subject
headings, and location, call number, and status.
Subject
Search.
Library of Congress subject headings appear in the same place in every
Orbis record, and tell us what the book is about. They are assigned by
librarians when the book is catalogued for the collection and are taken
from a controlled vocabulary, like a thesaurus, maintained by the Library
of Congress. This controlled vocabulary ensures that all books on the
same subject will be assigned the same subject heading.
A subject
search in Orbis finds books on the same topic by searching only the subject
heading fields in an Orbis record for whatever term you type in. Try searching
biography as a subject. The first screen is a guide screen. Click
on 1 to see the index screen. Notice the list of other ways to
search for information about biographies (search also under); if
you decide one of these is really what you want, you can execute the search
by clicking on the line number (automobile racing-biography). The
order of terms is very important in a subject search. Try looking for
bilingual education. Orbis will respond with the message that the
correct subject heading is education bilingual.
Keyword
Search.
The fourth major way to search Orbis is by keyword. Keyword is very useful
when you don't know an exact title or all parts of an author's name or
the correct subject heading. It is the only search in Orbis that allows
you to combine terms using Boolean operators (AND, OR, NOT). When you
search by author, title, or subject heading, Orbis looks in only those
parts of the record (the author, title, or subject heading fields). When
you search by keyword, Orbis searches in all parts of the record for the
term you type in. For example, a keyword search on rivers will
find records for books with rivers in the title or written by someone
named Rivers or about rivers in general. See the Orbis
Help Guide for more information on keyword searching.
