Be advised that the District of Columbia Public Library has established a new protocol limiting access control to the MLK Library Administrative Fourth Floor.  Consequently, contractors attempting to inquire about solicitations, attend bid openings and/or respond to solicitations need to factor in the requisite time necessary to be in compliance with said protocol.  Effective immediately, all contractors will be required to check in and be validated by the Public Safety Officer stationed at the entrance to the MLK Library.  Contractors need to include this processing time when responding to solicitations and complying with the established deadlines for bids and proposals.
