Some folk are confused, but OpenCitations and the Initiative for Open Citations, despite the similarity of their names, are two distinct organizations.

Good news!  Today, on January 16th 2018, Oxford University Press (OUP) announced its participation in the Initiative for Open Citations, and requested Crossref to turn on reference sharing for all OUP deposited references from more than half a million publications.  Oxford University Press is the largest university press in the world, publishing in 70 languages and 190 countries.

On 9th January 2018, I published a World View article in Nature entitled Funders should mandate open citations [1], in which I argue that access to open references from scholarly publications is so important that, when encouragements from organisations such as the Initiative for Open Citations (I4OC) to publishers to open their references fall on deaf ears, then sterner measures are required.

Two significant barriers prevent comprehensive reference availability through Crossref. The first barrier First, two-thirds of Crossref’s publisher-members, in particular the smaller ones, do not submit references along with the other details of their publications. Many of these published works are of types (e.g. abstracts, editorials and news items) that lack any references.

Since 1st January 2018, Crossref has had a new reference distribution policy, described at https://www.crossref.org/reference-distribution/. There are three possible options for setting the reference distribution preference from which a publisher can choose, these being ‘Closed’, ‘Limited’ and ‘Open”. If the ‘Closed’ option is chosen, the references will only be used for the Crossref Cited-by service, and are not distributed via any of the

For completeness, this post, also based on analyses performed by Daniel Ecer of eLife (d.ecer@elifesciences.org) on data he downloaded from Crossref in September 2017 (Ecer, 2017), complements the two preceding posts, and details the openness of references from scholarly publishers other than Elsevier.

Yesterday (November 23rd 2017) I was working with Daniel Ecer of eLife (d.ecer@elifesciences.org) to dig some hard facts out of the analyses he undertook on data he downloaded from Crossref in September 2017 (Ecer, 2017).  Because of its dominant position in the scholarly publishing world, in this, the second of two related posts, I report the results for references from works published by Elsevier.

The analyses show that, of the 33,672,763 journal articles documented in Crossref that have accompanying

The OpenCitations Enhancement Project funded by Sloan The Alfred P. Sloan Foundation, which funds research and education in science, technology, engineering, mathematics and economics, including a number of key technology projects relating to scholarly communication, has agreed to fund The OpenCitations Enhancement Project , a new project to develop and enhance the OpenCitations Corpus.

This post introduce two exemplar queries for interrogating the OpenCitations Corpus.

OpenCitations are pleased to announce the launch of the Initiative for Open Citations (I4OC) , a fresh momentum in the scholarly publishing world to open up data on the citations that link research publications.  OpenCitations are proud to be a founder of I4OC, and we encourage those remaining publishers whose journal article reference lists are still closed to embrace this sea change in attitude towards open citation data.
