Abstract: Most people’s images of librarianship are limited to the buildings, books, and staff of public and academic libraries. Law fi rm librarianship is an unfamiliar fi eld. What do law fi rm librarians do? They search and manage legal information so that attorneys can competently resolve their clients’ legal problems. This involves the application of librarianship’s general tools and knowledge to law-related print and digital material. This straightforward defi nition needs to be supplemented with an awareness of the fi eld’s particular work setting. Firm librarianship is heavily infl uenced by the technological, organizational, economic, and occupational frameworks in which it practices. This “environmental” or interactional standpoint requires an understanding of its immediate contexts: the law fi rm, the law fi rm library itself, the legal publishing industry, and the legal research world. A timely and informative account of law fi rm librarianship will examine its evolving roles, tasks, and objectives as it engages with its social and material surroundings.
