The Northumbria Pathfinder has just released an interim version of their cost modelling tool. You can read more about it and download it here
This tool is intended to help establish an internal business case to set up an APC fund for Open Access publishing. It allows you to model different cost projections based on variables such as FTE, number of articles, REF submission targets, and % Green vs Gold OA.
It is a development of initial work undertaken Northumbria University in 2014 which led to the University Executive approving a £100K/annum internal fund for Gold Open Access costs.
The project anticipates that this will be most useful to institutions which have received a lower/no block grant from RCUK, but there may be other use cases that we have not yet considered.
The tool is still under development and the project would welcome any comments or questions about this tool in order to improve and widen usability.
Please email Mark Harland (firstname.lastname@example.org) or leave a comment on the blog post above if you have any questions, comments, suggestions or feedback.
