Bibliometricians have long recurred to citation counts to measure the impact of publications on the advancement of science. However, since the earliest days of the field, some scholars have questioned whether all citations should value the same, and have gone on to weight them by a variety of factors.
However sophisticated the operationalization of the measures, the methodologies used in weighting citations still present limits in their underlying assumptions. This work takes an alternate approach to resolving the underlying problem: the proposal is to value citations by the impact of the citing articles.
As well as conceptualizing a new indicator of impact, the work illustrates its application to the 2004-2012 Italian scientific production indexed in the WoS.
The new indicator appears highly correlated to traditional field normalized citations, however the shifts observed between the two measures are frequent and the number of outliers not at all negligible. Moreover, the new indicator seems to show greater « sensitivity » when used in identification of the top-cited papers.

The advancement of science and technology has impacted functioning of the libraries of higher educational institutions, and the mode of providing resources for various academic activities.
For many years, libraries attached to educational institutions have been labouring with the question of how to determine the value of journals in their specific library collection. The Health Sciences Library of Manipal Academy of Higher Education at Manipal, subscribed a vast number of online journals for their users.
A relation between the usage and citations of subscribed online journals might provide a basis for the collection management in the libraries of academic and research institutions.
The current study resolved to identify whether relationship exists between usage of subscribed online journals and their citations in the academic publications of the health science professionals from 2010 to 2015.
The study found a statistically significant relationship between subscribed online journal usage and their citations in the publications through the inferential test of Spearman’s rank-order correlation.
For collection development of online journals, libraries can utilise the usage or citation data of journals as a decision making tool.

Researchers may describe different aspects of past scientific publications in their publications and the descriptions may keep changing in the evolution of science. The diverse and changing descriptions (i.e., citation context) on a publication characterize the impact and contributions of the past publication.
In this article, we aim to provide an approach to understanding the changing and complex roles of a publication characterized by its citation context. We described a method to represent the publications’ dynamic roles in science community in different periods as a sequence of vectors by training temporal embedding models.
The temporal representations can be used to quantify how much the roles of publications changed and interpret how they changed.
Our study in the biomedical domain shows that our metric on the changes of publications’ roles is stable over time at the population level but significantly distinguish individuals. We also show the interpretability of our methods by a concrete example.

The distribution of scientific citations for publications selected with different rules (author, topic, institution, country, journal, etc.) collapse on a single curve if one plots the citations relative to their mean value.
We find that the distribution of shares for the Facebook posts re-scale in the same manner to the very same curve with scientific citations. This finding suggests that citations are subjected to the same growth mechanism with Facebook popularity measures, being influenced by a statistically similar social environment and selection mechanism.
In a simple master-equation approach the exponential growth of the number of publications and a preferential selection mechanism leads to a Tsallis-Pareto distribution offering an excellent description for the observed statistics.
Based on our model and on the data derived from PubMed we predict that according to the present trend the average citations per scientific publications exponentially relaxes to about 4.

The accumulation of evidence that open access publishing can increase citation rates highlights one benefit of universal accessibility to scholarly works. However, studies investigating the effect of open access publishing on citations are typically conducted across a wide variety of journals and disciplines, introducing a number of potential issues and limiting their utility for specific disciplines.
Here, I used three primary marine ecology journals with an open access option as a “microcosm” of scientific publishing to determine whether or not open access articles received more citations than non-open access articles during the same time frame, controlling for self-citations, article type, and journal impact factor.
I also tested for the effects of time since publication and the number of authors. Citations were positively correlated with time since publication and differed across the three journals. In addition, open access articles received significantly more citations than non-open access articles.
Self-citations increased with author number and were affected by a complex interaction between open access, journal, and time since publication. This study demonstrates that open access articles receive more citations in hybrid marine ecology journals, although the causal factors driving this trend are unknown.

An experiment run in 2009 could not assess whether making monographs available in open access enhanced scholarly impact. This paper revisits the experiment, drawing on additional citation data and tweets. It attempts to answer the following research question: does open access have a positive influence on the number of citations and tweets a monograph receives, taking into account the influence of scholarly field and language?
The correlation between monograph citations and tweets is also investigated. The number of citations and tweets measured in 2014 reveal a slight open access advantage, but the influence of language or subject should also be taken into account. However, Twitter usage and citation behaviour hardly overlap.

This note presents data from the 1science oaIndx on the average of relative citations (ARC) for 3.3 million papers published from 2007 to 2009 and indexed in the Web of Science (WoS).
These data show a decidedly large citation advantage for open access (OA) papers, despite them suffering from a lag in availability compared to paywalled papers.
