Research Information Network and Universities UK have produced a new guide to provide advice on paying open access publication charges: that is, fees levied by some journals for the publication of scholarly articles so that they can be made available free of charge to readers, immediately upon publication.

The guide also sets out recommendations for universities and other research institutions, publishers, research funders, and authors.
JISC have also published a report on the economics of open access publishing:
