OpenCitations [1], the EXCITE Project [2] and Europe PubMed Central [3] are pleased to announce a Workshop on Open Citations at the University of Bologna in Bologna, Italy [4] on 3-5 September – https://workshop-oc.github.io. Format and topics Day One and Day Two: Formal presentations and discussions on the creation, availability, uses and applications of open bibliographic citations, and of bibliometric

OpenCitations is very pleased to announce its collaboration with four new scholarly Research and Development projects that are early adopters of the recently updated OpenCitations Data Model, described in this blog post.

Requirements for citations to be treated as first-class data entities In my introductory blog post, I listed five requirements for the treatment of citations as first-class data entities.  The fifth and final of these requirements is that there must be a Web-based identifier resolution service that takes the citation identifier as input and returns a description of the citation.

Requirements for citations to be treated as First-Class Data Entities In my introductory blog post, I listed five requirements for the treatment of citations as first-class data entities.  The fourth of these requirements is that they must be identifiable using a global persistent identifier scheme.

Requirements for citations to be treated as First-Class Data Entities In my introductory blog post, I listed five requirements for the treatment of citations as first-class data entities.  The third of these requirements is that they must be storable, searchable and retrievable in an open database designed for bibliographic citations.

Requirements for citations to be treated as First-Class Data Entities In my introductory blog post, I listed five requirements for the treatment of citations as first-class data entities.  The second of these requirements is that they must have metadata structured using a generic yet appropriately detailed data model.

Requirements for citations to be treated as First-Class Data Entities In my introductory blog post, I listed five requirements for the treatment of citations as first-class data entities.  The first of these requirements is that they must be definable in a machine-readable manner as a member of the class “Citation”, and describable using appropriate ontology terms.

Citations are now centre stage As a result of the Initiative for Open Citations (I4OC), launched on April 6 last year, almost all the major scholarly publishers now open the reference lists they submit to Crossref, resulting in more than half a billion references being openly available via the Crossref API.

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.
