This book explores the aspirational principles and actual practices concerning lawyersβ pro bono service. It begins from the premise that both the profession and the public have much to gain from reducing the gap between ideals and institutions. To that end, the book provides the first broad-scale study of the factors that influence American lawyersβ pro bono work, including an original empirical survey of over 3,000 lawyers. Attention is focused on the workplace factors and law school experiences that encourage charitable public interest activities. The book also includes the first comparative study of public service by looking at volunteer work by other professionals and by lawyers in other countries. Part I of the book explores the literature on altruistic commitments among the public in general, and lawyers in particular. Part II traces the evolution of attorneysβ pro bono responsibilities. Part III presents findings of the empirical survey. Part IV draws on these findings, together with prior research, to propose strategies for increasing and improving lawyersβ pro bono activity.
