ALT By opening CACM to the world, ACM hopes to increase engagement with the broader computer science community and encourage non-members to discover its rich resources and the benefits of joining the largest professional computer science organization. This move will also benefit CACM authors by expanding their readership to a larger and more diverse audience. Of course, the community’s continued support of ACM through membership and the ACM Open model is essential to keeping ACM and CACM strong, so it is critical that current members continue their membership and authors encourage their institutions to join the ACM Open model to keep this effort sustainable.
