Improving Access to Web Archives through Innovative Analysis of PDF Content
Date: April 2013
Creator: Phillips, Mark Edward & Murray, Kathleen R.
Description: This paper discusses improving access to web archives through innovative analysis of PDF content. Abstract: In 2008 five United States institutions collaborated to archive the U.S. federal government Web presence: the Library of Congress, the Internet Archive, the California Digital Library, the Government Printing Office, and the University of North Texas (UNT). Their objective was to document the changes coincident with the shift in leadership of the U.S. executive branch. The five partners identified key resources from the U.S. .gov Top Level Domain and completed crawls from September 2008 until March 2009. The resulting End of Term (EOT) 2008 Web Archive, a 16 TB dataset, was distributed to partners interested in providing local services and access to the archive. The UNT Libraries investigated Portable Document Format (PDF) files, a class of content many information professionals associate with the traditional notion of “discrete documents”. Over four million unique PDF documents were extracted from the Archive and a series of metadata and information extraction processes were conducted for each document. Additionally, derivative raster images of the first page of each document were created. These metrics were ingested into a database for further analysis, which brought to light previously hidden characteristics of the ...

Digital Preservation of Newspapers: Findings of the Chronicles in Preservation Project
Date: October 2012
Creator: Skinner, Katherine; Schultz, Matt; Halbert, Martin & Phillips, Mark Edward
Description: In this paper, the authors describe research led by Educopia Institute regarding the preservation needs for digitized and born-digital newspapers. The 'Chronicles in Preservation' project, builds upon previous efforts (e.g. the U.S. National Digital Newspaper Program) to look more broadly at the needs of digital newspapers in all of their diverse and challenging forms. This paper conveys the findings of the first research phase, including substantive survey results regarding digital newspaper curation practices.

Patron Driven Acquisitions: Or I Wish I Knew Then...
Date: August 2012
Creator: Avery, Beth & Harker, Karen
Description: This paper accompanies a poster presentation on patron driven acquisitions. The ups and downs of initiating and assessing a patron acquisitions program at the University of North Texas (UNT) will be highlighted. Emphasis will be placed on changing the philosophy of collection development, how to start the program (through a jobber or direct), coordinating print and electronic acquisitions processes, and assessing the first year's purchases.

Classifying the End-of-Term Archive
Date: June 2012
Creator: Murray, Kathleen R. & Hartman, Cathy Nelson
Description: This paper discusses the Classification of the End-of-Term Archive project. Abstract: For users, selecting relevant content from Web archives is often a daunting endeavor. This Institute of Museum and Library Services (IMLS) funded research project, Classification of the End-of-Term Archive, investigated whether link analysis and the cluster analysis were effective techniques for classifying the materials in the EOT Archive to improve discovery. Classification of the resulting clusters by subject matter experts in government information indicated that the structural analysis was not effective at creating clusters of related websites when authored by four or fewer federal government parent agencies. The results also suggested that cluster analysis might be effective at identifying topically related websites across agency authors, which would be highly desirable to both system developers and users. To investigate this, subject matter experts applied subject tags to the websites in two sets of machine-generated clusters. The findings indicate that the cluster analysis successfully identified strongly related content in 61% of clusters.

Measuring the Impact of Preserving Digital Assets
Date: June 2012
Creator: Murray, Kathleen R. & Belden, Dreanna
Description: This paper discusses measuring the impact of preserving digital assets. Abstract: The Portal to Texas History is a gateway to humanities collections within the digital library of the University of North Texas (UNT) Libraries (http://texashistory.unt.edu). Currently, materials from more than 190 content partners are available and the number of partners continues to grow. While ever-increasing numbers of partners and assets are signs that digitally preserving and making resources Web-accessible is a desirable thing, universities, cultural heritage institutions, and funding agencies increasingly expect measurements that report the impact and value resulting from digitizing and preserving assets. Because the Portal is fairly unique in both the number and scope of its content partners, it serves as a good case study for measuring the impact of digitization for two key digital library stakeholder groups: content providers and users. This paper reports the initial findings of a study of the impact of digitizing assets, specifically: (a) a framework of impact areas and indicators, (b) findings for the Portal's content partners and users.

Studying Distance Students: Methods, Findings, Actions
Date: April 20, 2012
Creator: Wahl, Diane; Avery, Beth & Henry, Lisa
Description: This paper discusses studying distance students. University of North Texas (UNT) Libraries began studying the library needs of distance learners in 2009 using a variety of approaches to explore and confirm these needs as well as obtain input into how to meet them. Approaches used to date include analysis of both quantitative and qualitative responses by online students to the LibQUAL+ surveys over time, focus groups, observations and interviews. The Libraries administered the LibQUAL+ survey and conducted focus groups. The Librarians then worked with two graduate level qualitative analysis classes, one on campus and one online, to do further study that included additional focus groups, observations, and interviews. The effectiveness, strengths and problems encountered with each method, as well as with the technology used in executing them, are covered. Triangulation of the results of the various methods to confirm findings is discussed as are the actions that are being taken to address the findings.

Lessons Learned: Digitization of Cooke County Ledgers
Date: March 2012
Creator: Barker, Trista; Berrios, Reyes; Fisher, Sarah Lynn; Krahmer, Ana & Tarver, Hannah
Description: This paper describes a grant project to digitize Cooke County, Texas ledgers. The project was funded in part by the National Historic Publications and Records Commission (NHPRC) and involves digitizing and hosting several rare and unique collections representative of the Civil War. The UNT Archives partnered with the UNT Libraries Digital Projects Unit (DPU), which managed all stages of the digitization. This paper describes and examines the process the DPU implemented to digitize the Cooke County ledger collection; in doing so, it provides insight into the problems one might encounter, as well as recommendations for institutions that may be considering similar digital projects.

Organizational Alignment
Date: May 23, 2011
Creator: Angevaare, Inge; Gallinger, Michelle; Anderson, Martha; Giaretta, David & Halbert, Martin
Description: This paper discusses organizational alignment. Digital preservation is not just a technical issue: there are also many organizational implications that must be addressed. This essay first identifies requirements that distinguish successful from unsuccessful modes of organizing digital preservation and long-term access, then presents a series of case studies that examine examples of addressing those requirements. These case studies all represent cooperative or collaborative approaches, in keeping with current research that demonstrates that institutions must share the financial and organizational burden of digital preservation in order to make it cost-effective. The case studies are drawn both from Europe and the United States, and include both single repository solutions and distributed preservation networks. A special role is played by so-called "enabling institutions" - national or regional initiatives established to raise awareness of the issues and promote cooperation in research and development. The essay concludes by considering possible areas for community alignment and next steps.
