APS has implemented the COUNTER Release 5 (R5) Code of Practice to provide the most up-to-date usage statistics service and reporting available. Subscribers can now access and download both R5 and R4 reports to evaluate their usage data by visiting https://librarians.aps.org/ and logging in. The R5 reports will be available for usage back to January 2017, and the R4 reports will continue to be available through January 2021.

The new R5 reports now available are:
* Title Master Report (TR)
* Journal Requests (Excluding OA_Gold) (TR_J1)
* Journal Access Denied (TR_J2)
* Journal Usage by Access Type (TR_J3)
* Journal Requests by YOP (Excluding OA_Gold) (TR_J4)
