Are you familiar with DCDL's Outreach Services Branch? This is a group of dedicated library staff who bring the library to patrons who can't make it into our facilities. They deliver books, DVDs and other library materials to facilities such as preschools, daycares and senior living centers.
They are also incredibly creative! Check out this foldable mini-Bookmobile they created, and feel free to print one out for yourself or your kids.
