Somehow, I completely missed (until just a few days ago) the existence of the truly cool Cascadilla Proceedings Project (emphasis added):
Cascadilla Proceedings Project is an imprint of Cascadilla Press. We created CPP as a new model for proceedings of linguistics conferences and workshops. All proceedings published by CPP are available both in print and on the web. Web access is free and unrestricted, and the copy available on the web is the same as the book version in content, formatting, and pagination. The print edition is a hardback which meets library binding standards. This combination allows for the best of both worlds: free and quick access for researchers looking for a proceedings paper, with all the advantages of being published in book form.
Among several other conference proceedings, there are those from the 2nd Laboratory Approaches to Spanish Phonetics and Phonology.
You may already be familiar with Cascadilla Press from recent book/CD proceedings of WCCFL and several other conferences, their Mac/PC-friendly Arboreal and Moraic fonts, or their fun teaching tools like IPA Bingo and Magnetic Phonetics. Now there’s just all the more reason to love the good folks at Cascadilla. While you’re browsing their site, consider buying a classroom IPA chart (or a t-shirt, coffee mug, etc.) at their new Cafe Press site. (And don’t forget to tell ’em phonoloblog sent you.)
