Terms of Usage - Digital Library
Users of the ACM Digital Library are asked to abide by the ACM Copyright
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 made or distributed for profit or commercial advantage and
they bear the ACM copyright notice. You may assemble and distribute links that
point to works in the ACM Digital Library.
Please 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 permissions@acm.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.
Please 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 Portal. ACM reserves the right to
suspend, or even cancel your subscription, if systematic downloading is
discovered.
