SPARC eNews Bulletin January 2017

Save the dates: SPARC General Assembly 2018
The 6th SPARC General Assembly is being organised in Kyoto, Japan, on 1-6 October 2018 (exact dates to be confirmed). General Assemblies are opportunities for SPARC to take stock of what has been achieved, where gaps in the portfolio of research undertaken by SPARC need to be filled, and to define where SPARC needs to be moving to remain responsive to the needs of both its members and the users of SPARC research products. The programme and further information will be published soon.
