Free journals published by the California Straw Building Association are available on their website as PDF downloads. Only issues from 2007-2012 are available at this time. I’m not sure if the journal is still published. The issues I looked at are quite good. To give you an idea of the content, the first article in the list is titled ‘Straw Bale House Designed by CASBA Members Arkin Tilt Architects Wins Fine Homebuilding Magazine’s “Best New Home” of 2012’.
