The changing role of libraries
Libraries are collections of books, manuscripts, journals,
and other sources of recorded information. They commonly include
reference works, such as encyclopaedias that provide factual
information and indexes that help users find information in
other sources; creative works, including poetry, novels, short
stories, music scores, and photographs; nonfiction, such as
biographies, histories, and other factual reports; and
periodical publications, including magazines, scholarly
journals, and books published as part of a series. As home use
of records, CD-ROMs, and audiotapes and videotapes has
increased, library collections have begun to include these and
other forms of media, too.
Libraries were involved early in exploiting information
technologies. For many years libraries have participated in
cooperative ventures with other libraries. Different
institutions have shared cataloging and information about what
each has in its collection. They have used this shared
information to facilitate the borrowing and lending of materials
among libraries. Librarians have also become expert in finding
information from on-line and CD-ROM databases.
As society has begun to value information more highly, the
so-called information industry has developed. This industry
encompasses publishers, software developers, on-line information
services, and other businesses that package and sell information
products for a profit. It provides both an opportunity and a
challenge to libraries. On the one hand, as more information
becomes available in electronic form, libraries no longer have
to own an article or a certain piece of statistical information,
for example, to obtain it quickly for a user. On the other hand,
members of the information industry seem to be offering
alternatives to libraries. A student with her own computer
can now go directly to an on-line service to locate, order, and
receive a copy of an article without ever leaving her home.
Although the development of digital libraries means that
people do not have to go to a building for some kinds of
information, users still need help to locate the information
they want. In a traditional library building, a user has access
to a catalog that will help locate a book. In a digital library,
a user has access to catalogs to find traditional library
materials, but much of the information on, for example, the
Internet can not be found through one commonly accepted form of
identification. This problem necessitates agreement on standard
ways to identify pieces of electronic information (sometimes
called meta-data) and the development of codes (such as HTML
[Hypertext Markup Language] and SGML [Standard Generalized
Markup Language]) that can be inserted into electronic texts.
For many years libraries have bought books and periodicals
that people can borrow or photocopy for personal use. Publishers
of electronic databases, however, do not usually sell their
product, but instead they license it to libraries (or sites) for
specific uses. They usually charge libraries a per-user fee or a
per-unit fee for the specific amount of information the library
uses. When libraries do not own these resources, they have less
control over whether older information is saved for future
use--another important cultural function of libraries. In the
electronic age, questions of copyright, intellectual property
rights, and the economics of information have become
increasingly important to the future of library service.
