5/14/20 Delivery Update!

Dear MLS members,

We would like to share an update with you regarding Delivery. MLS and Optima have been discussing ways to address the increased volume at libraries. At this time, we are working on efforts to alleviate volume prior to the resumption of delivery (No date has be set).  In order to ease the volume capacity at libraries, warehouses and trucks, we are scheduling pick-ups for higher volume libraries in a series of phases. We are currently reaching out to libraries to set up delivery pick-ups. Please wait to hear from us. Pick up is optional. We ask for your patience as we begin this process.

Parts of our plan, including specific dates, may be adapted once the Governor releases his Guidelines for reopening the State and in consultation with the members about their plans. We will continue to update as the process moves forward.
