When Amanda Oliver began work as a school librarian, fueled by a lifelong love of books and a desire to help, she felt qualified for the job. What she learned was that librarians are expected to serve as mediators and mental-health-crisis support professionals, customer service reps and administrators of overdose treatment, fierce loyalists to institutionalized mythology and enforced silence, and arms of state surveillance.

Based on firsthand experiences from six years of professional work as a librarian in high-poverty neighborhoods of Washington, DC, as well as interviews and research, Overdue begins with Oliver's first day at Northwest One, the DC Public Library branch where she would ultimately end her library career.

Through her experience at this branch, Oliver highlights the national problems that have existed in libraries since they were founded, troublingly at odds with the common romanticization of the library as a shining beacon of equality: racism, segregation, and economic oppression. These fundamental American problems manifest today as police violence, the opioid epidemic, widespread inaccessibility of affordable housing, and a lack of mental health care nationwide—all of which come to a head in public library spaces.

Can public librarians continue to play the many roles they are tasked with? Can American society sustain one of its most noble institutions?
