Records come in a
variety of shapes, sizes, and types, such as hand-copied
ledger books, newspaper files, and various forms created
over time to record information for licenses, court
orders, and permits. Unstable or heavily used records
may require transfer to another format, such as
microfilm or permanent paper, to ensure preservation of
the information they contain.
Microfilm
Records are
microfilmed to preserve their information, reduce wear
and tear on originals, save space, and improve access.
Copies of film can be distributed to off-site locations,
providing access to more than one user at a time. Some
records retention schedules allow for the early disposal
of records once microfilmed. If properly processed and
stored, black-and-white, saver gelatin microfilm has a
usable life of about 500 years, far longer than the
useful life of many poor-quality original paper
records. Even if original paper records were damaged,
stolen, or destroyed, the information from those records
would still survive if the originals had been filmed and
stored in a safe, preferably off-site, location.
Selection
Microfilm all
vital records. Vital records are those that are
essential to the resumption or continuation of
operations (or, both); to the recreation of the legal
and financial status of government in the organization;
or to the protection and fulfillment of obligations that
the, organization has made. Vital records are among the
permanent records for which an organization has
long-term responsibility.
Typical vital
records include board minutes and tax, birth, Marriage,
deed, and death records. Also regard inventories and
finding aids as vital records. Many record schedules
indicate which records are vital.
Historical
societies and courthouses often keep files of local
newspapers that are in poor
Condition and
consume a considerable amount of space. They are ideal
candidates for microfilming. Many community newspapers
are already available on microfilm through the Newspaper
Project funded by the National Endowment for the
Humanities. Before investing limited resources to film
published materials, first check local and regional
repositories and databases to see if the items have
already been filmed. The State Historical Society of
1owa has an extensive collection of this microfilm.
Because of
their value as artifacts, you should also preserve
newspapers printed prior to the Civil War in their
original format.
Microfilm
Service Companies
Microfilming is
a technically, complex and labor-intensive operation. In
addition to the obvious expense of cameras, microfilming
requires equipment for processing and copying, and there
must be bibliographic and technical assessments of the
completed films. Microfilm personnel need appropriate
training. Equipment demands ongoing maintenance to
produce completed film, which will meet required
standards. It is possible that a professional microfilm
service company can microfilm records more economically
than setting up an in-house operation.
It is vitally
important to evaluate the qualifications of any
microfilm service company. Network with other record
custodians and inquire about their experiences with
microfilming agents. Contact potential agencies by
phone. Question them about their experience filming
records that are bound, fragile, or oversized. Ask the
microfilming agent for at least three references from
other government agencies or historical societies and
contact these organization's to see how the vendor
handled records, met deadlines, and responded to
refilming corrections. Visit the microfilm vendor's
operation. Ask questions about standards, procedures,
and security.
Physical
Preparation
Microfilm must
contain all of the information, as it appears on an
original record. Filming is conducted so that all
individual documents and groups of documents maintain
their numerical or sequential order. Correct order is
essential to ensure that microfilmed records will be
accepted as evidence in a court of law.
In most cases
the records repository will prepare materials prior to,
filming and contract with a microfilm service company
for the actual filming of the records. Before filming,
remove all paper clips, staples, and other fasteners
from the records. Gently open and flatten all records in
preparation for filming. Use a soft white brush to
remove from the records any surface dirt that might
reduce resolution or sharpness of the final microfilmed
image.
Take the time
to verify that records are prepared in the correct order
to be filmed. Note where records are incomplete,
illegible, or misnumbered, and be sure to provide this
information to the microfilm service agency with the
records to be filmed.
Bibliographic
Preparation
An indexing
system is usually required for finding records on a reel
of microfilm. Micrographics standards require
eye-legible targets at the beginning of a reel that
state the name of the government or agency that is the
creator of the records on the film, the title of the
record series, and its inclusive dates. Targets must
also be included to indicate any irregularities in the
original records. Targets can be prepared by the
microfilm service agency from information supplied by
the office repository.
Once records
have been filmed, remember to change your finding aids
to direct users to request microfilm rather than the
originals.
Contracts
A written
contract will outline specific requirements and describe
the record series to be filmed. Include cubic feet or
number of items, if known. Specify in this contract that
all work must be done according to the standards
established by the Association for Information and Image
Management.
Research
several companies and determine whether other agencies
were pleased with the quality of their work. Solicit
bids for the project from at least three companies.
Standards
Micrographics
standards define exactly what should happen in the
microfilming process to ensure that the end product is
of the highest possible. Standards prescribe appropriate
targets,
targets,
density and. resolution, film quality, processing, and
quality control. The standards also prescribe the
creation of a camera negative (security copy), a
printing negative (reproduction copy), and use copies.
All microfilm whether produced by a microfilm service
company or in house, must meet these standards.
Digital
Scanning
While scanning
records for electronic use allows access by multiple
users and saves space, digital scanning requires an
expensive commitment to supporting technologies used to
convert and retrieve records. Moreover, digital
technology is not yet standardized, and new developments
are continually occurring. Microfilm is a stable
technology and a proven method for preserving records.
Microfilm records first. At a later date, the microfilm
copy can be scanned for ready access as needed.
Photocopying
Photocopying is
another way to preserve the informational content of
records. Records on poor-quality papers and those
generated by thermofax copying processes or
pressure-transfer forms are unstable.
Transfer
information from these records to alkaline papers that
meet the American National Standards Institute (ANSI)
standard for permanent paper, Z39.48-1991. Such
papers are readily available from paper distributors
upon request. Copying onto stable alkaline paper will
help to ensure the long-term preservation of the
information contained in a record.
Make all
preservation photocopies using a black and white copy
machine. Color photocopies may not be stable over the
long term.
Create
Surrogates for Research Use
As a records
custodian, you are protecting the rights of both present
and future users to have access to records. Continued
use of originals can prevent future access to
information if records become damaged through excessive
wear. Make photocopies to serve as "use
copies," or surrogates for the originals. Write
policies so that users have only limited access to
originals when surrogates are available and explain to
users why you are taking this extra care.
When making
surrogates, never send original records through a
document feeder on a photocopier. If it is
necessary to feed oversized records through a copying
machine designed exclusively for this purpose, place
original documents in protective polyester sleeves prior
to duplication.
