"The editorial boards of various academic journals in
linguistics are in the process of leaving their publishers or are
renegotiating their collaboration. They will soon be publishing their
articles on a universal free access basis at extremely low costs.
Supported by universities, this unique initiative will be launched under
the name of LingOA and is a significant step on the road towards open
access."
