PurposeThe study has been undertaken with the purpose of finding out the growth and characteristics of digital library literature.Design/methodology/approachOver 1,000 articles for the period 1998‐2004 were collected from LISA Plus and were analyzed to study authorship patterns, authors' productivity and prominent contributors, language‐wise and year‐wise distribution of articles, country‐wise distribution of journals, core journals in the subject area, and indexing term frequency.FindingsSome of the important findings are that most articles (61 percent) are single‐authored; author productivity is not in agreement with Lotka's Law, except in one case where number of articles is three; the maximum number of articles were published in 2003 with English being the most productive language; maximum articles were published in the journal D‐lib Magazine; distribution of articles nearly follows Bradford's Law; and USA ranked first for maximum number of journals.Originality/valueThe paper is relevant to those interested in bibliometrics and provides a comprehensive overview of authorship in the library and information science community.
PurposeThe purpose of this research is to identify and evaluate the collections within digital libraries and repositories in India available in the public domain.Design/methodology/approachThe digital libraries and repositories were identified through a study of the literature, as well as internet searching and browsing. The resulting digital libraries and repositories were explored to study their collections.FindingsUse of open source software especially for the creation of institutional repositories is found to be common. However, major digital library initiatives such as the Digital Library of India use custom‐made software. The collection size in most digital libraries and repositories is in a few hundreds.Practical implicationsThe paper highlights the state of digital libraries and repositories in India in late 2007.Originality/valueThe paper is the first of its kind that attempts to identify and evaluate digital libraries and repositories in India. It also gives a comprehensive listing of digital libraries and institutional repositories in India available in the public domain.
BackgroundSince many years, various bonding attachments have been used as a mode of traction for surgically exposed impacted teeth. It has always been a challenge to select an attachment considering predictability of the bonded attachment, mucogingival and periodontal conditions of the overlying tissues, and additional inventory requirement.MethodsA 0.010-in. stainless steel ligature wire with eyelets at one end and spiral twisted at the other end was made and used as an attachment to guide surgically exposed impacted canine.ResultsOrthodontic guided eruption of an impacted canine of a 16-year-old patient using this simple attachment with 1-year follow-up illustrates adequate amount of attached gingiva.ConclusionsLigature wire attachment is a simple inexpensive attachment that can be custom made without any need for additional inventory, besides being more comfortable to patients.
PurposeThe purpose of this paper is to demonstrate the new application of a performance index (p‐index), extending its use to libraries for measuring and evaluating library circulation statistics in terms of quality and quantity of library books usage by subjects.Design/methodology/approachThe study uses NISCAIR library circulation data and computes p‐index as well as h‐index for comparing usage in different subjects.FindingsThe results indicate that a two dimensional map of quality vs quantity of transactions can be used for better understanding and evaluation of library usage.Research limitations/implicationsThe h‐ and p‐indices and the quality‐quantity maps can be used as a benchmark for monitoring library performance in addition to finding out high value areas in the library collection, high value users, and high value books.Practical implicationsThe paper is able to supplement the insights normally available from routine statistical analysis of circulation data.Originality/valueThis study may help in providing knowledge/insights in building up collections.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
