Despite the fact that 160,000 people are locked up in the United States federal correctional facilities, practical information about the federal prison system remains difficult to locate. While some information may be found scattered on the Internet, in directions given at court, or through shared personal experience, there is no single source available that is a collection of all available information. The U.S. Federal Prison System is the first comprehensive reference work that includes official prison policies, first-person accounts from prisoners, and information about each federal facility.

In the past 30 years, the population of prisoners in the United States has expanded almost 5-fold, correctional facilities are increasingly overcrowded, and more of the country's disadvantaged populations—racial minorities, women, people with mental illness, and people with communicable diseases such as HIV/AIDS, hepatitis C, and tuberculosis—are under correctional supervision. Because prisoners face restrictions on liberty and autonomy, have limited privacy, and often receive inadequate health care, they require specific protections when involved in research, particularly in today's correctional settings. Given these issues, the Department of Health and Human Services' Office for Human Research Protections commissioned the Institute of Medicine to review the ethical considerations regarding research involving prisoners. The resulting analysis contained in this book, Ethical Considerations for Research Involving Prisoners, emphasizes five broad actions to provide prisoners involved in research with critically important protections: • expand the definition of "prisoner"; • ensure universally and consistently applied standards of protection; • shift from a category-based to a risk-benefit approach to research review; • update the ethical framework to include collaborative responsibility; and • enhance systematic oversight of research involving prisoners.
