From the GPO:
The Depository Library Council (DLC) to the GPO Director, upon the close of the 2019 Depository Library Council Virtual Meeting, began work on developing formal recommendations and commendations for the U.S. Government Publishing Office (GPO). On May 29, 2019, two recommendations and one commendation were presented. These were reviewed and discussed in detail by GPO staff, and formal GPO responses are now available via FDLP.gov.
