Impact factor – a numerical measure that indicates the average number of citations to articles published over the previous two years in a journal, and frequently used as a proxy for a journal’s relative importance.
Bibliometrics is the branch of library and information science concerned with the application of mathematical and statistical analysis to bibliography. Bibliometrics involves the statistical analysis of books, articles, or other publications.
Article-level metrics – all types of article-level metrics including download and usage statistics, citations, and article-level altmetrics
Altmetrics are alternative ways of recording and measuring the use and impact of scholarship. Rather than solely counting the number of times a work is cited in scholarly literature, alternative metrics also measure and analyze social media (e.g., Facebook, Twitter, blogs, wikis, etc.), document downloads, links to publishing and unpublished research, and other uses of research literature, in order to provide a more comprehensive measurement of scholarships reach and impact.
Registered Reports – A type of publication in which peer review of the suggested method is completed prior to data collection and analysis. Accepted papers then are guaranteed publication in the journal if the authors follow through with the registered methodology.
Double blind peer review – when the reviewers don’t know who the authors are, and vice versa.
Portable peer review – independent peer review that travels with a manuscript that is submitted to subsequent different journals, designed to combat redundancy in the peer review process.
Signed peer review – when the individual reviews are publicly signed by those who conducted them.
