Preservation in the age of large-scale digitization
Get PDFThe digitization of millions of books under programs such as Google Book Search and Microsoft Live Search Books is dramatically expanding our ability to search and find information. The aim of these large-scale projects?to make content accessible?is interwoven with the question of how one keeps that content, whether digital or print, fit for use over time.
This report by Oya Y. Rieger examines large-scale digital initiatives (LSDIs) to identify issues that will influence the availability and usability, over time, of the digital books these projects create. Ms. Rieger is interim assistant university librarian for digital library and information technologies at the Cornell University Library.
The paper describes four large-scale projects?Google Book Search, Microsoft Live Search Books, Open Content Alliance, and the Million Book Project?and their digitization strategies. It then discusses a range of issues affecting the stewardship of the digital collections they create: selection, quality in content creation, technical infrastructure, and organizational infrastructure. The paper also attempts to foresee the likely impacts of large-scale digitization on book collections
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Key Issue
No full textA few months ago, while I was participating in a conference about open access infrastructures, a delegate from a governmental agency asked, “Why does each library need to maintain a repository for their own scientists?” He was rightfully wondering if a broad collaboration in building a network of archives will provide a durable and extensible technology and service framework for ever-increasing digital scholarly content. The ensuing discussion did not offer a plausible response but accentuated that we do not have in place a plan for building an expandable infrastructure to facilitate communication and exchange of information among rapidly proliferating distinct instances of institutional and subject repositories
Enduring Access to Special Collections: Challenges and Opportunities for Large-Scale Digitization Initiatives
No full textAs we explore the evolving information landscape and institutional context of rare and manuscript collections, one of the critical matters is to consider the implications of large-scale digitization initiatives (LSDIs) for our programs. Although most LSDI efforts thus far have focused on general collections, it is inevitable that the attention will soon be turned to special collections. With the current networked information environment and increasing reliance on digital content subscriptions, rare and manuscript collections increasingly define the uniqueness and character of individual research libraries. The goal of this article is to characterize current LSDIs and discuss the potential implications for . . .</jats:p
