News
- Due to the high volume of subject proposals received and an increasingly heavy workload, the Policy, Training, and Cooperative Programs Division (PTCP) has decided temporarily to limit the number of proposals that can be scheduled to each LCSH monthly list, effective immediately. The limit will be 200 proposals. Once that cap is reached each month, only proposals associated with CIP cataloging will continue to be scheduled for the list; other proposals will be held until the following list. (There will be no limit on classification proposals unless they have corresponding LCSH proposals.) We regret that this will result in a delay in scheduling some proposals for a list, but we hope at least it will result in a faster turnaround time for processing each list. PTCP appreciates the community’s support and patience. If you have questions or comments about this temporary measure, please contact [email protected].
