<p>ACM has among the most liberal publishing policies of any scholarly publisher today. Over the years, our policies have evolved and been adapted to maintain this reputation as a forward thinking publisher. This policy reflects ACM’s non-profit and mission-based approach to publishing high quality information for the computing community, with an emphasis on wide-spread distribution and access.</p><p>Consistent with ACM’s general Publishing Policy, most recently updated on April 2, 2013, all ACM Books authors shall be given the option of signing a copyright transfer Agreement or an exclusive license to publish Agreement, as part of their Author Publishing Agreement with ACM Books.</p><p>Authors of ACM Books will be given the option of signing a Publication Agreement that includes a "Transfer of Copyright" provision or a version that includes an “Exclusive Right to Publish” provision instead of transferring copyright to the Publisher. Authors should consider both options and discuss them with either ACM or M&C if they have questions regarding the relative benefits of either version of the Publishing Agreement.</p><p>For more detailed information about ACM’s general publishing policies or author rights, please visit the following websites:<br><a href="http://authors.acm.org/main.html">http://authors.acm.org/main.html</a><br><a href="http://www.acm.org/publications/policies/copyright_policy">http://www.acm.org/publications/policies/copyright_policy</a></p>
