Late life is characterized by great diversity in memory and other cognitive functions. Although a substantial proportion of older adults suffer from Alzheimer's disease or another form of dementia, a majority retain a high level of cognitive skills throughout the life span. Identifying factors that sustain and enhance cognitive well-being is a growing area of original and translational research.
In 2009, there are as many as 5.2 million Americans living with Alzheimer's disease, and that figure is expected to grow to as many as 16 million by 2050. One in six women and one in 10 men who live to be at least age 55 will develop Alzheimer's disease in their remaining lifetime. Approximately 10 million of the 78 million baby boomers who were alive in 2008 can expect to develop Alzheimer's disease. Seventy percent of people with Alzheimer's disease live at home, cared for by family and friends. In 2008, 9.8 million family members, friends, and neighbors provided unpaid care for someone with Alzheimer's disease or another form of dementia. The direct costs to Medicare and Medicaid for care of people with Alzheimer's disease amount to more than $148 billion annually (from Alzheimer's Association, 2008 Alzheimer's Disease Facts and Figures).
We now catalog in a post-AACR2 world. RDA: Resource Description and Access is designed to cover all types of content and media, but communities of practice are still evolving for motion picture and video materials. This handbook clarifies the protocol for DVDs and Blu-ray discs, expanding upon established guidelines for AACR2 and integrating them into the new standard. Along the way, Higgins introduces the fundamentals of filmmaking, including its history and technical vocabulary, providing context that will help catalogers quickly find the information relevant to their bibliographic records. Organized by familiar MARC 21 fields, this comprehensive reference walks readers through such topics as Unraveling the complexity of film and the ways it is packaged and presented on optical disc, to help quickly determine the title statement and statement of responsibility Explaining the roles of the individuals and organizations involved in the creation and publication of film, and where to record them in catalog records Deciphering the technical terms and abbreviations used on DVDs and Blu-ray discs Using subject and genre headings Cataloging television and streaming media Dealing with unusual formats, such as videotape and reels of photochemical film Outlining the MARC 21 fields where AACR2 practices differed from RDA With the expert guidance contained in this book, readers will learn how to apply RDA instructions to the cataloging of every type of film and video collection, whatever the medium.
