The short answer
A charge from ACM* DIGITAL LIBRARY SUB represents an annual professional membership or digital library subscription to the Association for Computing Machinery.
ACM Digital Library Billing
When the statement descriptor ACM* DIGITAL LIBRARY SUB appears on a credit card or bank statement, it indicates an authorized billing from the Association for Computing Machinery. This organization manages professional computing research and publishes specialized journals. The transaction usually covers the ACM Membership & Library Plan, which provides access to their extensive database of peer-reviewed articles, computing literature, and SIGGRAPH conference proceedings.
Most individuals incur these fees when renewing their annual professional or student dues. The society operates on a subscription model where members pay upfront for twelve months of continuous digital access. Because the billing cycle automatically renews by default, cardholders often see this charge exactly one year after their initial registration or after upgrading from a basic membership to a full-text research tier.
If you do not recognize the transaction, check with colleagues or university students in your household who might have used your payment method to download specific conference papers or pay Special Interest Group affiliate dues. You can verify the exact invoice details, manage your renewal settings, and cancel future payments by logging into the society's member portal.
