The document discusses digitization practices at the State Library of Arizona. It explains the differences between preservation and archival approaches to digitization. Preservation focuses on reproducing the information content while archival focuses on maintaining the original document characteristics. The document also describes the different scanners used for digitization, including their advantages and disadvantages. Color versus black and white scanning is discussed, as well as a hybrid approach. The digitization approach depends on factors like access needs, personnel, and budget. Digitized materials are crosslinked between the library catalog and a digital archive project.

- 8. Ricoh Copier/Scanner Good • Relatively fast “pass” • Can change resolution mid scan • Document feeder – Can quickly scan ring bound items – Makes many reports from 1970’s – 1990’s very easy to scan Bad • Lowest image quality • Black and white only • No OCR • Does not do graphics or photos well • Size • Document feeder can damage items MCLC TechTalk Feb. 27, 2014 Peter Grant pgrant@azlibrary.gov Vinny Alascia valascia@azlibrary.gov
- 9. Plustek Book Scanner Good • Color • Can accommodate bindings • Can OCR • Higher image quality than Ricoh Bad • Low processor power limits to smaller documents • Finicky touch screen • Primarily a text scanner • Cannot change resolution mid-scan MCLC TechTalk Feb. 27, 2014 Peter Grant pgrant@azlibrary.gov Vinny Alascia valascia@azlibrary.gov
- 10. Zeutschel Omniscan Good • Color • OCR • Can accommodate fragile material and tight bindings • Very high image quality • Very customizable Bad • Complicated • Slow pass • Files can be large MCLC TechTalk Feb. 27, 2014 Peter Grant pgrant@azlibrary.gov Vinny Alascia valascia@azlibrary.gov
- 11. Black and White or Color? MCLC TechTalk Feb. 27, 2014 Peter Grant pgrant@azlibrary.gov Vinny Alascia valascia@azlibrary.gov
- 12. Black and White Advantages Drawbacks The original is black and white Can lose detail Smaller file size Cannot accurately portray color, photos, graphics, etc. Contrast can be adjusted MCLC TechTalk Feb. 27, 2014 Peter Grant pgrant@azlibrary.gov Vinny Alascia valascia@azlibrary.gov
- 13. Color Advantages Drawbacks Can make some older documents easier to read Color will make for a larger file size. Can preserve the information of the original – for example a color graph will still be in color. Color can be difficult or expensive for the user to print. Color can make some low- contrast black and white documents more readable. A color scan may appear to decrease the overall contrast of a black and white document making it more difficult to read.MCLC TechTalk Feb. 27, 2014 Peter Grant pgrant@azlibrary.gov Vinny Alascia valascia@azlibrary.gov
