This document discusses digital imaging and factors to consider for digitizing records. Digital imaging converts documents to computer-readable digital image files consisting of pixels arranged in rows and columns. Key factors to consider include the project's mission and users, priorities for speed, quality and quantity, and staff expertise. Maintaining records as digital images allows for high-density storage, faster retrieval when indexed, and multiple access levels, but images require computer equipment to read and involve equipment and scanning costs. Proper implementation requires selecting materials, preparing files, creating metadata, quality control, and staff training.

2. What is digital imaging ?
Digital imaging is a process by which a document is
converted from a human-readable format to a
computer-readable digital image file.

3. A digital image consists of pixels
arranged in columns or rows.
 Pixel bit depth
Resolution
Compression
Master images and access images
Optical character recognition (OCR)

4. What factors must be considered in determining
whether to image records?
Before starting any imaging project, know the :
Project's mission
Users
Priorities (speed, image quality, and quantity), and
functional goals (reference, web use, publication,
other).
Additionally, assess staff expertise and availability (to
do scanning, manage infrastructure, migrate data,
and build metadata)
Address content issues, such as physical condition,
format, nature and attributes to be captured.

5. What are possible advantages and disadvantages
of maintaining records as images?
Ability to use very high-density storage media.
Shorter retrieval time than hard copy when the
images are well indexed.
Multiple users and access levels are possible.
Low shipping costs and ease of information
dissemination.
Digital images don't lose quality from generation
to generation. (Well made copies and derivatives
can be as good as the original images.)

6. Digital images are not human-readable without
computer equipment.
Significant equipment costs, including hardware
and software.
Different types of scanners must be used to scan
text, oversize items, photographic prints, slides,
and other formats.

7. Image storage
Online
Near- line
Offline

8. Preservation strategies
Migration/ conversion
Technology emulation
Technology preservation

9. Implementation strategy
Selection of materials to be digitized.
Preparation of materials, including sorting files,
removing staples and paperclips, weeding out
unnecessary materials, and conservation of any
deteriorating documents.
Creation of standardized metadata.
Quality control of source materials and digital
images.

10. Staff training on new hardware and/or software.
Determine if the records are adequately organized.
Make certain that the records were properly filed
and correct all miss-filings before imaging.
