Linguistics in Open Access (LingOA) is an organisation dedicated to 'flipping' existing subscription journals in linguistics to Fair Open Access.
LingOA currently comprises 4 journals: Glossa, Laboratory Phonology, Journal of Portuguese Linguistics, and Italian journal of linguistics
LingOA has two sister organisations, MathOA and PsyOA, who pursue the same goals in the fields of mathematics and psychology. All three organisations are part of the Fair Open Access Alliance (FOAA)
I am a board member of all four organisations, and the president of LingOA and FOAA.
