The Thomas Jefferson Library maintains a lost and found container at the Public Service Desk. Lost items are held for a short period and then sent to the Lost and Found Center (Information Desk) in the Millennium Student Center. Wallets, purses, cell phones, car keys and other items of significant value (e.g. wallets, keys, laptops, phones, etc.are immediately given to campus police.
The Research Commons Computer Lab also collects items lost within the lab area. Check with the lab consultant if you think you might have left something in one of the labs.
