Digital libraries such as the NASA Astrophysics Data System (Kurtz et al., 2005) permit the easy accumulation of a new type of bibliometric measure, the number of electronic accesses (“reads”) of individual articles. We explore various aspects of this new measure. We examine the obsolescence function as measured by actual reads and show that it can be well fit by the sum of four exponentials with very different time constants. We compare the obsolescence function as measured by readership with… 
How the Literature is Used A View Through Citation and Usage Statistics of the ADS
Using the citation and usage statistics from the NASA Astrophysics Data System, the impact of offering a paper as an electronic pre-print on the arXiv e-print repository, prior to its publication in a scholarly journal is studied.
Analysis of the Obsolescence of Citations and Access in Electronic Journals at University Libraries
No strong correlation between citations and access is observed in most fields with regard to the short-term obsolescence, and comparatively strong and significant correlations are seen in natural sciences other than medicine-related fields.
Comparison of downloads, citations and readership data for two information systems journals
Comparing downloads from ScienceDirect, citations from Scopus and readership data from the social reference management system Mendeley for articles from two information systems journals published between 2002 and 2011 suggests that there is at least “some” difference between the two usage measures and the citation impact of the analysed information systems articles.
Effect of E-printing on Citation Rates in Astronomy and Physics
It is shown that for a number of major astronomy and physics journals the most important papers are submitted to the arXiv e-print repository first.
Relationship between downloads and citations at journal and paper levels, and the influence of language
The results showed that downloads have limited utility as predictors of citation since it is in the early years when any correlations have the least significance.
Citation Classification And Its Applications
A machine learning approach to automatically classifying citations according to authors' motivations is presented and the approach makes use of the structure and the argumentative nature of the scientific papers.
On full text download and citation distributions in scientific‐scholarly journals
A statistical analysis of full text downloads of articles in Elsevier's ScienceDirect covering all disciplines reveals large differences in download frequencies, their skewness, and their correlation
Eigenfactor: ranking and mapping scientific knowledge
The Eigenfactor algorithm is proposed, which takes into account not only how many citations a journal receives but also where those citations come from, similar to how Google ranks web pages, but instead of ranking websites, the authors rank journals and instead of using hyperlinks, they use citations.
Bibliometrics to webometrics
The distance that bibliometrics has travelled since 1958 is reviewed by comparing early bibliometric practice with current practice, and by giving an overview of a range of recent developments, such as patent analysis, national research evaluation exercises, visualization techniques, new applications, online citation indexes, and the creation of digital libraries.
Download indicators represent a great potential due to the high amount of download data that can be collected that can provide a great statistical significance. The relationship between citation and


Determining the publication impact of a digital library
This investigation failed to establish a relationship between LTRS and increased citations and raises at least as many questions as it answers, but it hopes it will serve as an invitation to, and guide for, further research in the use of DLs.
A compendium of issues for citation analysis
This paper examines a number of the criticisms that citation analysis has been subjected to over the years. It is argued that many of these criticisms have been based on only limited examinations of
The NASA Astrophysics Data System: Overview
The NASA Astrophysics Data System Abstract Service has become a key component of astronomical research. It provides bibliographic information daily, or near daily, to a majority of astronomical
Changes in the Use of Literature with Time--Obsolescence Revisited
Citation studies confirm the great variation in citation decay between subjects and types of article and also show that the sources used for citations affect the results of analyses.
Using Article Photocopy Data in Bibliographic Models for Journal Collection Management
This article describes a method for analyzing the demand for photocopies of individual journal articles for the purpose of making journal selection, deselection, and retention decisions and found that very few users accounted for more than half the photocopy requests.
Citebase Search: Autonomous Citation Database for e-Print Archives
Citebase is a culmination of the Opcit Project and the Open Archives Initiative to develop a cross-archive search engine with the ability to harvest, parse, and link research paper bibliographies, and is integrated with
Progress in Documentation the Complexities of citation Practice: a Review of citation studies
This review focusses on the citation studies that have explored the complexities and the underlying norms of the citation process, and the studies which have dealt with citation functions, citation quality, citation concepts and citation motivation.
Library journal use and citation half-line in medical science
This study investigated the in-house use half-life of journals in the Library of Veterans General Hospital, Taipei, and their citation half-life, and the difference between them. The use study
The NASA Astrophysics Data System: The search engine and its user interface
The ADS Abstract and Article Services provide access to the astronomical literature through the World Wide Web with sophisticated searching capabilities that allow users to find references in the fields of Astronomy, Physics/Geophysics, and astronomical Instrumentation and Engineering.
Terminology and parameters for describing the relation between figures for the use of library literature and for its age are discussed, and the need to relate terminology more closely to the facts they represent is stressed.
