I work at a company called DeepDyve; we work with publishers to provide alternative (cheaper) access models to their content. We have an online-only viewer and let you view articles for a limited amount of time (we call it a rental). If you are interested, please give it a shot and let me know how sufficient of an alternative it is. We currently allow 1 free rental (which will work for our ACM content), but we'll be adding free trials for our subscription plans instead very soon. http://www.deepdyve.com http://www.deepdyve.com/browse/publishers/association-for-co...
