DL End-user Policy
Users of the ACM Digital Library are asked to abide by the ACM Author Rights and Publishing Policy, paying particular attention to the permissions statement.
You may make digital or hard copies of the individual articles that you are entitled to access for personal or classroom use, as long as the copies are not sold to the students and they bear the appropriate ACM copyright or license notice. You may assemble and distribute links that point to works in the ACM Digital Library.
Do not republish these ACM works, or post them on other servers, or redistribute them to lists, without first getting explicit permission from ACM. Contact firstname.lastname@example.org. Please do not abuse your access rights to the ACM Digital Library by wholesale duplication of all or substantial sections of the ACM Digital Library.
Do not use robots or intelligent agents: they degrade the performance of the system for everyone, and are not a proper use of the ACM Digital Library. ACM reserves the right to suspend, or even cancel your subscription, if systematic downloading is discovered. ACM also reserves the right to block access to the Digital Library for IP addresses from where such activities are found to be originating.
