ImpactStory is an open source, web-based tool that provides altmetrics to help researchers measure the impacts of their research outputs including journal articles, blog posts, datasets, and software.[2] It aims to change the focus of the scholarly reward system to value and encourage web-native scholarship. ImpactStory is a nonprofit organisation funded by the Alfred P. Sloan Foundation [3] and the National Science Foundation.[4]

ImpactStory follows open practices with its data (to the extent allowed by providers' terms of service), code,[5] and governance.[6]

It provides context to its metrics so that they are meaningful without knowledge of the specific dataset: for example, instead of letting the reader guess whether having five forks on GitHub is common, ImpactStory would tell that the repository is in the 95th percentile of all GitHub repositories created that year.[7]

The metrics provided by ImpactStory can be used by researchers who want to know how many times their work has been downloaded and shared,[8] and also research funders who are interested in the impact of research beyond only considering citations to journal articles.


Unpaywall is a browser extension,[9] which find free versions of (paywalled) articles.[10] In July 2018 it was reported to provide free access to 20 million articles,[1] and about 47% of the articles that people search with Unpaywall.[11] In June 2017 it was integrated into Web of Science and in July 2018 Elsevier announced plans the same month to integrate the service into the Scopus search engine.[1]

In scholarly and scientific publishing, altmetrics are non-traditional bibliometrics proposed as an alternative or complement to more traditional citation impact metrics, such as impact factor and h-index. The term altmetrics was proposed in 2010, as a generalization of article level metrics, and has its roots in the #altmetrics hashtag. Although altmetrics are often thought of as metrics about articles, they can be applied to people, journals, books, data sets, presentations, videos, source code repositories, web pages, etc. Altmetrics use public APIs across platforms to gather data with open scripts and algorithms. Altmetrics did not originally cover citation counts, but calculate scholar impact based on diverse online research output, such as social media, online news media, online reference managers and so on. It demonstrates both the impact and the detailed composition of the impact. Altmetrics could be applied to research filter, promotion and tenure dossiers, grant applications and for ranking newly-published articles in academic search engines.

Cambia (non-profit organization)

Cambia is an Australian-based global non-profit social enterprise focusing on open science, biology, innovation system reform and intellectual property. Its projects include the Patent Lens, its successor The Lens, and the Biological Innovation for Open Society Initiative.

Cambia derives its name from the Spanish verb cambiar, to change.


Figshare is an online open access repository where researchers can preserve and share their research outputs, including figures, datasets, images, and videos. It is free to upload content and free to access, in adherence to the principle of open data. Figshare is one of a number of portfolio businesses supported by Digital Science.


The ORCID iD (Open Researcher and Contributor ID) is a nonproprietary alphanumeric code to uniquely identify scientific and other academic authors and contributors. This addresses the problem that a particular author's contributions to the scientific literature or publications in the humanities can be hard to recognize as most personal names are not unique, they can change (such as with marriage), have cultural differences in name order, contain inconsistent use of first-name abbreviations and employ different writing systems. It provides a persistent identity for humans, similar to that created for content-related entities on digital networks by digital object identifiers (DOIs).The ORCID organization, ORCID Inc., offers an open and independent registry intended to be the de facto standard for contributor identification in research and academic publishing. On 16 October 2012, ORCID launched its registry services and started issuing user identifiers.
