Jinny Williams, recent high school graduate, is also graduated from page girl to Junior Library Assistant at the Ranford (New Jersey) Public Library. As a non-professional worker, Jinny's duties are largely clerical though she soon discovers that the official definition of her job hardly encompasses all the situations she is required to meet. There is an attempt to add color and romance to the story, but the prime purpose of the book is to present the scope of library work to future non-professionals in the field. A respect for books, an interest in serving the public, patience with children and a combination of flexibility and tenaciousness are the outstanding requisites. Because of the day by day dramatization of typical library situations, this is recommended chiefly to those who are unable to approach librarianship professionally but feel they would like to find some career in this field.
