This book was compiled and edited by a librarian who was instrumental in getting funding from a Library Services and Technology Act grant to carry out an internship program in public libraries. The grant allowed the MCLS consortium of public libraries in the Los Angeles area to place library school students in paid internships in MCLS member libraries. The successful program was called 'From Interns to Library Leaders' (FILL), and led in part to this book, which offers firsthand 'advice from the field' provided by former public library interns and internship site supervisors. Contributors include a diverse group of voices and representative experiences from around the country, who had either worked as or supervised a student intern in one of the many fields of public librarianship (e.g., public services, children's, technical services, branches, etc.). The result: eighteen chapters written by practitioners and library school faculty, who generously share what it's like to participate in a public library internship.
