What is a COST Action?

COST is the longest-running European framework supporting trans-national cooperation among researchers, engineers and scholars across Europe.

It is a unique means for them to jointly develop their own ideas and new initiatives across all fields in science and technology, including social sciences and humanities, through pan-European networking of nationally funded research activities.

How do I apply for financial support for open access publications?

As announced a few months ago, we have the possibility to support open access publications, provided that:

– The authors are from at least 3 COST Countries

– The publication is open access

– The publication acknowledges the COST Action NQO

It is assumed that the authors are members of the COST Action (at least one per COST Country), because the aim is to support the dissemination of scientific results originating from the COST Action.

It is possible that we will not be able to fully cover your publication charges. That depends on the number of requests and on the total amount.

If you fulfill these conditions and would like to receive financial support, please send a copy of the invoice and of the paper by the end of September to  .
