ACM SIGACCESS Newsletter October 2015 "The SIGACCESS Newsletter is a regular online publication of SIGACCESS. We encourage a wide variety of contributions, such as: letters to the editor, technical papers, short reports, reviews of papers of products, abstracts, book reviews, conference reports and/or announcements, interesting web page URLs, local activity reports, etc. Actually, we solicit almost anything of interest to our readers. Material may be reproduced from the Newsletter for non-commercial use with credit to the author and SIGACCESS. You may publish your work here before submitting it elsewhere. We are a very informal forum for sharing ideas with others who have common interests."
