The open access movement has been slow in reaching the linguistics community. However, things are changing. Elsevier, the publisher that made 1,2 billion € in net profit in 2011 (a 6% increase form 2010 in times of financial crisis!) may be publishing English for Specific Purposes, for example, but there are high quality open access journals too (Iberica, Revista de Lengua para Fines Específicos or LSP Journal) and their numbers are increasing.
I’m really glad that things have started to change in the business of publishing open access monographs. Initiated by Stefan Müller and Martin Haspelmath, the OALI project aims to publish and store books on linguistics in a digital format (print on demand will be also available by Create Space and others). The team are planing to use the Creative Commons CC BY copyright, however, translation rights would remain with the author. OALI is hosted at the Freie Universität Berlin.
The project is in need of donations although they have applied for German state funding (DFG) too. If you support the Open access movement, you can help in different ways: publish a book with them, review books for them, donate money, typesetting, etc., or just tell them you support the project.
