NOTEBOOK - NOTE #A8: MICROFORMS
MICROFORMS are a way of
preserving and storing large amounts of print information in a
condensed format. Periodicals and books may be photographed in a
reduced scale and the resulting microcopies are magnified using
special readers. Microforms are considered more stable and
long-lived than most electronic (computer)
files.
There are two general types of
microforms.
MICROFICHE
Small sheets of special
plastic support the photographs of the pages. These are
approximately 4 by 6 inches in size. Each microfiche may contain
many pages of information.
MICROFILM
Microfilm is a long strip of
film onto which information is copied. The spools of film are often
used for archiving newspapers.
WHAT IS
AVAILABLE
Libraries collect microforms
for several reasons. The major one is a space saving device,
especially for seldom used periodicals. It is also a way of
acquiring copies of information no longer available in regular
print. Back issues of a journal are an example. Some documents are
only disseminated as microfiche or microfilm.
Though somewhat less
convenient than traditional books, newspapers or periodicals,
microforms contain much valuable information. High quality microform
readers, such as those in the Busse Center Library, facilitate their
use.
Among the most used items on
microfilm are newspapers like the New York Times.
Imagine the stack of newspapers which would be necessary to store
and to search when a specific article is needed. The rolls of
microfilm are easy to use when to alternatives are
considered.
The same is true for
microfiche. A 4 x 6 inch microfiche may store many pages from books
or issues of journals.
The Busse Center Library keeps
back issues of some journals on microfiche. The MMC Periodicals
List indicates whether the back issues are bound or on microfilm
or microfiche. There is also a collection of Moody’s Manuals
and a small selection of ERIC Documents in
microforms.
ASSISTANCE
Ask at the Reference Desk for
assistance in finding information and in using the Microfilm and
Microfiche readers. It is possible to make photocopies using the
reader-printers. |
