Summary
  • During the course of the work day, I help in the
    creation of microfilm and microfiche (they are
    also collectively called microforms). A planned
    move from the microfilm format to the imaging
    format for the office is to be implemented within
    the next three years (barring the unforeseen).
    There are some distinct advantages and
    disadvantages to each system. This presentation
    will review the two methods and compare how they
    may fit in with library practices.

3
What is Microfilm/fiche?
  • Microfilm is film on which printed materials are
    photographed at greatly reduced size for ease of
    storage. It also refers to a reproduction on this
    kind of film or a magnification system used to
    read the material. Archival microfilm meets the
    demands of either the National Preservation
    Office Guide to Microfilming or the RLG Standards
    (in the USA)
  • Microfiche is a card or sheet of microfilm
    capable of accommodating and preserving a
    considerable number of pages in reduced form. It
    can also be a sheet of microfilm on which many
    pages of microfilm have been stored in jackets
    instead of being left on the film reel.

4
What are the advantages of Microforms?
  • Microfilm offers reassurance that the image on
    the film will be legible far into the future.
  • Archival microfilm meets the demands of either
    the National Preservation Office Guide to
    Microfilming or the RLG Standards (in the USA).
    Microfilm is the product of tested technology,
    governed by these standards. Microfilm boasts a
    life expectancy of 500 years when created and
    stored according to standard.
  • Microfilm is also robust, reliable,
    cost-effective and provides a solid foundation
    for scanning to other media.
  • Microfilm does not require sophisticated
    equipment for reading and access. In fact, even
    without standard microfilm/fiche viewers, It can
    easily be read with a light source and a
    magnifying glass.

5
More Microform Advantages
  • Microforms can enhance access to information that
    would otherwise be unavailable because the
    original item is at a distant site or is
    vulnerable to damage and/or loss through
    handling.
  • Microforms are relatively inexpensive to produce
    and to copy.
  • Microforms come in a number of formats. The most
    familiar of these are 16mm or 35mm roll microfilm
    and microfiche, the latter resembling a plastic
    file card.
  • Roll microfilm, in either 16mm or 35mm formats,
    can be cut into short strips and housed in clear
    "jackets" to produce a microfiche. Three types of
    film are common in microform collections
    silver-gelatin, diazo, and vesicular.

Microfilm creation process
  • First the paper is organized into the order it is
    to be filmed in and to a filming area. There each
    page is photographed.
  • This camera set-up is similar to what is used at
    my employment. There are both automated and hand
    filming cameras available. With hand cameras the
    papers are placed one by one and filmed with a
    button press. Automated cameras mechanically grab
    papers and films each page via sensors. Both
    types require constant attention and regular
    maintenance to ensure proper filming.

7
Microfilm creation process
  • Now the film needs to be developed. The machine
    depicted here is a processor for microfilm. The
    film is run from inside the top of the machine
    through six sets of rollers and vats of processor
    fluid, fixer fluid, and then water. By the time
    it comes out of the processor (about 15 minutes
    per film reel depending on the processor), it has
    dried and is wound onto the awaiting film reel.
  • Now the film is ready to be stored and viewed.

8
Microform viewers
  • Microform viewers come in a variety of shapes and
    sizes. Some viewers (like the one pictured here)
    have printers built into viewer to return the
    film to hard copy format when needed. Others only
    offer viewing capabilities and tend to be smaller
    then the viewer and printer models. This
    particular views is set up for microfiche and
    would need to have a reel attachment added to
    view a microfilm reel.

9
Microfiche creation and storage
  • Microfiche cards are slightly different in
    creation. The image is photographed directly onto
    the a film card and is then ready for storage
    without being developed in a separate processor.
    There picture here shows one of the common
    organizers for microfiche. This can also be used
    to store fiche.

10
More on storage
  • When there are many fiche to store, trays like
    the one here can be used.
  • The trays can then be stored in a standard file
    cabinet or in a cabinet with automated shelving.
    These shelves move in a circular rotation and
    helps to make an optimum use of available space.

11
What is Imaging?
  • Document imaging is the process by which a
    digital picture of the original paper document is
    created. Utilizing document scanning software,
    the document, when run through a scanner,
    converts to an electronic image. Sophisticated
    digital imaging software tools can also improve
    the quality of the document. It can remove
    speckles, straighten the documents, remove
    backgrounds that are obscuring the information,
    darken and lighten text.
  • While the quality of paper documents deteriorates
    over time, the quality of the electronic
    documents remain consistent. However, it is a
    read-only format. This feature eliminates
    deleting or changing original copies. Documents
    can be annotated or otherwise edited once the
    documents are copied to a hard drive or other
    read/write media. Such annotations are stored as
    overlays and do not alter the original image in
    any way.1

12
Imaging-Preparing
  • The imaging system also begins by sorting the
    paperwork to be filmed. But instead of being
    placed in the order to be filmed, it is separated
    by what type of information is on each page. To
    use a newspaper for an example, sections may be
    separated into categories such as sports,
    obituaries, features, business, community
    articles, education, entertainment, national
    events, reader input, state government, travel,
    and classifieds. These sample categories and
    others can be separated into subcategories if
    desired. The sorted bundle of papers receives a
    batch number to be used at the indexing stage.

13
Imaging-Scanning
  • The papers are now sent through one of two types
    of scanners.
  • The first is a high-speed scanner that quick
    scans neat-edged, one-sided papers.
  • The other is a desktop scanner that is hand fed.
    It is mainly used for pages that would cause
    problems in the high-speed scanner. Such pages
    may have text on both sides or bedraggled edges.

14
Imaging-Indexing
  • The scanned pages are now ready to be sorted in
    the computer system. The pages are looked up in
    the computer system via batch number. The
    sections, from the preparing stage, are then
    attached to the matching index file in the
    computer system and if needed the scanned images
    are enhanced to improve the quality of the
    digital duplicate.
  • The documents are now in the database for anyone
    with access to the system to retrieve. The papers
    can then be stored or disposed of as directed by
    the companies preferred policy. New paper copies
    can be printed from the database as needed
    through a computer printer.
  • To prevent loss of information, the databases are
    frequently backed-up in CD format and the CDs at
    kept at a separate archives location. This way if
    something should happen to either the database or
    the location of the database the information can
    be restored with minimal expense.

15
Libraries and Microforms
  • Microforms have been in libraries for decades.
    They have been used to store newspapers and other
    old documents for future use without risk of loss
    or damage to the original documentation.
  • With other advances in technology, microfilm
    seems to becoming an outdated mode of storing
    information. However since converting microfilm
    to digital images can be a costly venture and
    since the materials used to view microfilm are
    already in place, the use of microforms in
    libraries is not likely to disappear.

16
Libraries and Imaging
  • Despite its current place, libraries of the
    future may choose to replace microfilm with the
    digital imaging. Libraries will probably not go
    to the expense of setting up imaging stations and
    training staff, but they may choose to set up
    computers with imaging software and have the
    microforms sent out to an independent company to
    do the conversions.
  • The reason for this is mostly convenience.
    Imaging does not require the storage space of
    microforms. Nor does it require equipment outside
    of computers, printers, and software compared to
    the file cabinets, microform viewers or
    viewer/printers. Also due to the digital
    clean-up that can be done on documents, it can
    provide a tidier copy then microfilm.
  • However with the digital databases of articles
    and internet access to historical information
    available, there is probably not a need for
    current archival information to also be stored in
    either microform or imaging formats.
