From the report:
The American Library Association has a longstanding record of promoting library and information services to older adults. These guidelines, first developed in the 1970s, have been updated to respond to the changing demographics of an aging U.S. population. In 2007, one of every five persons was 55 years or older, or over 68 million people. The aging of the “baby boomers” will add to these numbers well into the next decade, and the lengthening of the average lifespan is creating several generations of older adults at a time that the United States has become more ethnically and linguistically diverse. As a result, the current population of older adults is the most heterogeneous in U.S. history. These updated guidelines reflect a basic principle in library services to older adults that recognizes this diversity and discourages stereotyping in planning collections, programs, and services for this growing population.
