Kentucky History on Microfilm
• Over 5,000 titles filmed as a part of the CPMP
• 1,500 titles from the Coleman bibliography
• 30,000 reels of historic newspapers and manuscripts

Digitization = Better Access
• Users really prefer access from the desktop
• Expands access
![Page 9: Beyond the Shelf : Providing Access to Historic Microfilmed Materials](https://reader035.vdocuments.us/reader035/viewer/2022062723/56813f7a550346895daa669b/html5/thumbnails/9.jpg)

“Okay”, we said, “You want it, we’ll make it!
First question: Do we create files from –
• Source documents (which are likely brittle, bound and guarded by that ogre librarian with the nasty cattle prod)
or….
• Microfilm (leaving the master negative in the vault where it’s safe while using the service negative, or print master)?
![Page 10: Beyond the Shelf : Providing Access to Historic Microfilmed Materials](https://reader035.vdocuments.us/reader035/viewer/2022062723/56813f7a550346895daa669b/html5/thumbnails/10.jpg)

The choice was obvious
Our pilot proved that microfilm is the fastest and safest method to provide access while preserving the source documents.

What we proposed…
A 2 year project to create a fully searchable digital page image archive of 950 rare historic Kentuckiana books using a microfilm to digital methodology.
![Page 13: Beyond the Shelf : Providing Access to Historic Microfilmed Materials](https://reader035.vdocuments.us/reader035/viewer/2022062723/56813f7a550346895daa669b/html5/thumbnails/13.jpg)

The case we made …
• Digital images ensure easy access and wide distribution
• This hybrid, standards based non-proprietary approach can serve as a model for cost effective access and preservation for published materials
![Page 14: Beyond the Shelf : Providing Access to Historic Microfilmed Materials](https://reader035.vdocuments.us/reader035/viewer/2022062723/56813f7a550346895daa669b/html5/thumbnails/14.jpg)
Mary Molinaro University of Kentucky Libraries [email protected]
The case we made …
• Students, teachers and scholars will use this material to support their research and teaching.
• Our collection has national significance and will be of interest to scholars and students outside Kentucky

Ramp up
• Hired 2 Image Management Specialists
• Trained staff

So, how do we make these things?
• First we scan!
• Mekel M525 scanner
• Using the service master negative
• Manual scans instead of automatic
• Scanner splits images into their respective pages
![Page 19: Beyond the Shelf : Providing Access to Historic Microfilmed Materials](https://reader035.vdocuments.us/reader035/viewer/2022062723/56813f7a550346895daa669b/html5/thumbnails/19.jpg)

Challenge #1
• Mekel scanner’s “turnkey system” operated exclusively with Windows NT
• Windows NT was a real drag!– Slow as molasses– Crashed frequently– The blue screen of death lurked about when
scanning grayscale images
• Windows 2000 greatly improved productivity – installed July 2003 and it hasn’t crashed yet!

Lessons Learned #1
• Quality matters!
• Quality costs!

Cataloging Thin Air
• All of the Beyond the Shelf digital books were cataloged before they were actually created.
• Derive electronic records using constant data from the microfilm bibs
• Create purls using the OCLC number of the microfilm bib as the unique identifier.

Challenge #2
• Migration from Dynaweb to DLXS– Loss of functionality that we had come to
know and love– No longer had to create derivative images
(DLXS creates on the fly)
• End of year one 22% only complete– Not really utilizing student employees
![Page 33: Beyond the Shelf : Providing Access to Historic Microfilmed Materials](https://reader035.vdocuments.us/reader035/viewer/2022062723/56813f7a550346895daa669b/html5/thumbnails/33.jpg)

Costs – cheaper than we had estimated!
Estimate• 200,000 pages• 950 volumes• $1.60-$2.25 per page• $342 per volume
Actual• 226,386 pages• 1,069 volumes• $ .47 per page• $91.50 per volume
![Page 34: Beyond the Shelf : Providing Access to Historic Microfilmed Materials](https://reader035.vdocuments.us/reader035/viewer/2022062723/56813f7a550346895daa669b/html5/thumbnails/34.jpg)
Mary Molinaro University of Kentucky Libraries [email protected]
How did this happen?
• We got better at the process
• We used students when we could
• DLXS streamlined the process
![Page 35: Beyond the Shelf : Providing Access to Historic Microfilmed Materials](https://reader035.vdocuments.us/reader035/viewer/2022062723/56813f7a550346895daa669b/html5/thumbnails/35.jpg)

Outcomes Based Evaluation
• Are Kentucky students learning better as a result of our project?
![Page 36: Beyond the Shelf : Providing Access to Historic Microfilmed Materials](https://reader035.vdocuments.us/reader035/viewer/2022062723/56813f7a550346895daa669b/html5/thumbnails/36.jpg)
Mary Molinaro University of Kentucky Libraries [email protected]
What did we learn?
• Scanning from film is a viable option
• We could migrate platforms successfully
![Page 37: Beyond the Shelf : Providing Access to Historic Microfilmed Materials](https://reader035.vdocuments.us/reader035/viewer/2022062723/56813f7a550346895daa669b/html5/thumbnails/37.jpg)

We believe
In short, we’re making good stuff for the right reason, the right way.

Next steps
• Digitizing the Coleman bibliography
• Moving from a project to a program
• Digitizing historic newspapers
