It also includes discussions of sexual issues for older persons as well as physically and mentally challenged individuals. The new countries covered include: Austria, Colombia, Croatia, Cyprus, Egypt, Hong Kong, Iceland, Indonesia, Italy, Korea, Morocco, Nigeria, Norway, Papua New Guinea, The Philippines, Portugal, Turkey, and Vietnam. As noted, the work also presents significant updates, by some 20 specialists, of the countries covered in Volumes 1 through 3--originally published in 1997--which take readers into the new millennium.This eagerly awaited Volume 4 to The International Encyclopedia of Sexuality makes this entire set an even more indispensable reference work for sexologists, psychotherapists, anthropologists, and anyone involved in cross-cultural studies.>
