  title={Crossref: The sustainable source of community-owned scholarly metadata},
  author={Ginny Hendricks and Dominika Tkaczyk and Jennifer Lin and Patricia Feeney},
  journal={Quantitative Science Studies},
This paper describes the scholarly metadata collected and made available by Crossref, as well as its importance in the scholarly research ecosystem. Containing over 106 million records and expanding at an average rate of 11% a year, Crossref’s metadata has become one of the major sources of scholarly data for publishers, authors, librarians, funders, and researchers. The metadata set consists of 13 content types, including not only traditional types, such as journals and conference papers, but… 
Impact factions: assessing the citation impact of different types of open access repositories
Institutional repositories (IR) maintained by research libraries play a central role in providing open access to taxpayer-funded research products. It is difficult to measure the extent to which IR

Identifying and correcting invalid citations due to DOI errors in Crossref data
The data gathered in this study can enable investigating possible reasons for DOI mistakes from a qualitative point of view, helping publishers identify the problems underlying their production of invalid citation data, and could be integrated into the existing process to add citations by automatically correcting a wrong DOI.

Integrating and Exploiting Public Metadata Sources in a Bibliographic Information System
Some insights are given how the dblp bibliography as an example for such a system is maintained and improved and how metadata can be automatically harvested from publisher websites and how the harvesting process can be steered.
Comparing published scientific journal articles to their pre-print versions
A comparative study of pre-print papers from two distinct science, technology, and medicine corpora and their final published counterparts revealed that the text contents of the scientific papers generally changed very little from their pre- print to final published versions.
Disciplinary differences of the impact of altmetric

The results show that articles in the General category attract more attention from social media, Social Sciences articles have higher usage than Physical Sciences, and General articles are more cited and saved than Health Sciences and Social sciences articles.
The practice of self-citations: a longitudinal study
The analysis showed an overall increment in author self-citations in several of the 24 academic disciplines considered, but depicted a stronger causal relation between such increment and the rules introduced by the 2012 Italian Scientific Habilitation in 10 out of 24 disciplines analysed.
