Astronomy & Astrophysics is indexed in CrossRef.

The CrossRef system is used for linking citations across publishers. To ensure direct linking to and from its contents, EDP Sciences now registers its scientific research journals to CrossRef. Online archives have also been indexed.

From now on, any CrossRef members can create direct links from its online references to the EDP Sciences contents, using CrossRef database. Reciprocally, the online references of EDP Sciences articles will include direct links to the cited articles. Such links can be created on condition that the reference of the cited article matches a CrossRef data. In particular these direct links only concern references whose publishers have previously indexed their own data to CrossRef.
