The Occupational Outlook Handbook (OOH for short) is revised and updated every two years -- it's consistently one of the most up-to-date occupational references available. The OOH is one of the best-known government publications. It's used by job seekers for career exploration and for resume and interview preparation. Counselors, teachers, and career coaches refer to it in their work with students and clients, and many who work in education and business settings routinely purchase the newest OOH edition. The book is an excellent resource for career-related activities and interests, and business people refer to the OOH when writing job descriptions, among other uses. Occupations in the OOH cover about 90% of the workforce. Thorough descriptions include nature of work, working conditions, employment, training, qualifications, advancement, ten-year job outlook, earnings, related occupations, and sources of additional information.
