Shared Print Analysis Tool at the Colorado Alliance of Research Libraries

The Colorado Alliance of Research Libraries has launched the Alliance Shared Print Trust and is in the process of developing a shared print analysis tool. The system allows libraries to compare themselves with other libraries that have added their MARC records so that they can easily and quickly determine what records are unique or held in common with other libraries. The comparison system is built on open source tools and has been embedded in the Gold Rush framework. The author provides a brief overview of other shared print analysis tools.

Library and Information Science Education and eScience: The Current State of ALA Accredited MLS/MLIS Programs in preparing Librarians and Information Professionals for eScience Needs

The purpose of this study is multifaceted: 1) to describe eScience research in acomprehensive way; 2) to help library and information specialists understand the realm of eScience research and the information needs of the community and demonstrate the importance of LIS professionals within the eScience domain; 3) and to explore the current state of curricular content of ALA accredited MLS/MLIS programs to understand the extent to which they prepare new professionals within eScience librarianship. The literature review focuses heavily on eScientists and other data-driven researchers’ information service needs in addition to demonstrating how and why librarians and information specialists can and should fulfill these service gaps and information needs within eScience research. By looking at the current curriculum of American Library Association (ALA) accredited MLS/MLIS programs, we can identify potential gaps in knowledge and where to improve in order to prepare and train new MLS/MLIS graduates to fulfill the needs of eScientists. This investigation is meant to be informative and can be used as a tool for LIS programs to assess their curriculums in comparison to the needs of eScience and other data-driven and networked research. Finally, this investigation will provide awareness and insight into the services needed to support a thriving eScience and data-driven research community to the LIS profession.

An Empirical Comparison of Reuse in Embedded and Nonembedded Systems

High-quality software, delivered on time and budget, constitutes a critical part of most products and services in modern society. Our government has invested billions of dollars to develop software assets, often to redevelop the same capability many times. Recognizing the waste involved in redeveloping these assets, in 1992 the Department of Defense issued the Software Reuse Initiative. The vision of the Software Reuse Initiative was "To drive the DoD software community from its current "re-invent the software" cycle to a process-driven, domain-specific, architecture-centric, library-based way of constructing software.'' Twenty years after issuing this initiative, there is evidence of this vision beginning to be realized in nonembedded systems. However, virtually every large embedded system undertaken has incurred large cost and schedule overruns. Investigations into the root cause of these overruns implicates reuse. Why are we seeing improvements in the outcomes of these large scale nonembedded systems and worse outcomes in embedded systems? This question is the foundation for this research. The experiences of the Aerospace industry have led to a number of questions about reuse and how the industry is employing reuse in embedded systems. For example, does reuse in embedded systems yield the same outcomes as in nonembedded systems? Are the outcomes positive? If the outcomes are different, it may indicate that embedded systems should not use data from nonembedded systems for estimation. Are embedded systems using the same development approaches as nonembedded systems? Does the development approach make a difference? If embedded systems develop software differently from nonembedded systems, it may mean that the same processes do not apply to both types of systems. What about the reuse of different artifacts? Perhaps there are certain artifacts that, when reused, contribute more or are more difficult to use in embedded systems. Finally, what are the success factors and obstacles to reuse? Are they the same in embedded systems as in nonembedded systems? The research in this dissertation is comprised of a series of empirical studies using professionals in the aerospace and defense industry as its subjects. The main focus has been to investigate the reuse practices of embedded systems professionals and nonembedded systems professionals and compare the methods and artifacts used against the outcomes. The research has followed a combined qualitative and quantitative design approach. The qualitative data were collected by surveying software and systems engineers, interviewing senior developers, and reading numerous documents and other studies. Quantitative data were derived from converting survey and interview respondents' answers into coding that could be counted and measured. From the search of existing empirical literature, we learned that reuse in embedded systems are in fact significantly different from nonembedded systems, particularly in effort in model based development approach and quality where the development approach was not specified. The questionnaire showed differences in the development approach used in embedded projects from nonembedded projects, in particular, embedded systems were significantly more likely to use a heritage/legacy development approach. There was also a difference in the artifacts used, with embedded systems more likely to reuse hardware, test products, and test clusters. Nearly all the projects reported using code, but the questionnaire showed that the reuse of code brought mixed results. One of the differences expressed by the respondents to the questionnaire was the difficulty in reuse of code for embedded systems when the platform changed. The semistructured interviews were performed to tell us why the phenomena in the review of literature and the questionnaire were observed. We asked respected industry professionals, such as senior fellows, fellows and distinguished members of technical staff, about their experiences with reuse. We learned that many embedded systems used heritage/legacy development approaches because their systems had been around for many years, before models and modeling tools became available. We learned that reuse of code is beneficial primarily when the code does not require modification, but, especially in embedded systems, once it has to be changed, reuse of code yields few benefits. Finally, while platform independence is a goal for many in nonembedded systems, it is certainly not a goal for the embedded systems professionals and in many cases it is a detriment. However, both embedded and nonembedded systems professionals endorsed the idea of platform standardization. Finally, we conclude that while reuse in embedded systems and nonembedded systems is different today, they are converging. As heritage embedded systems are phased out, models become more robust and platforms are standardized, reuse in embedded systems will become more like nonembedded systems.

Digitization for Preservation and Access: Restoring the Usefulness of the Nitrate Negative Collections at the American Geographical Society Library

Film-based photographic collections of nitrate negatives pose major challenges to preservation and access because of unstable media and the lack of item-level indexing. Digitization offers an opportunity to capture the content of deteriorating negatives, to extend access to them, and to restore their usefulness as information resources. Digitization as a preservation strategy has been the subject of ongoing debate. This article contributes to the discussion by exploring access to and the preservation of film-based photographic collections and by presenting the digiti- zation project at the American Geographical Society Library as a case study. The project, Saving and Sharing the AGS Library’s Historic Nitrate Negative Images, was undertaken from 2010 to 2012 to preserve and provide access to over 69,000 nitrate negatives from its historic collections.

Digital Curation Program of the Digital Public Library of America (DPLA)

The Digital Public Library of America (DPLA) is a digital library that strives to serve the public through digital collections accumulated from a wide variety of partners. Our chosen topic for the DPLA exhibit project is Perspectives on the Vietnam War. The Vietnam War remains a controversial topic of national interest, making it a topic of depth and of many perspectives. Our goals with this exhibit were to gather different perspectives of the war through personal stories, the media, presidential administrations of the war, military personnel, and the general public, including famous figures. We strove to demonstrate the variety of perspectives on the Vietnam War through a variation of digital objects and content that will be engaging for users: both black and white and color photos, videos, and audio files. Furthermore, we wanted to ensure that our digital materials are of high quality, properly documented, and easy to search and find thus all of our objects are from DPLA and are from usable original sources. This poster will describe our processes for organizational, object selection, building our exhibit, attainment of our goals, and detailed steps of our overall operation. The poster will also include details about the minor issues and bumps that occurred while reaching our final product as well as the team members’ perspectives on the project as a whole including: problems, words to for the wise, and triumphs.
