AIDS/HIV is part of the Information Plus Reference
Series. The purpose of each volume of the series is to
present the latest facts on a topic of pressing concern in
modern American life. These topics include today’s most
controversial and most studied social issues: abortion,
capital punishment, care for the elderly, crime, the environment,
health care, immigration, minorities, national
security, social welfare, women, youth, and many more.
Although written especially for the high school and undergraduate
student, this series is an excellent resource for
anyone in need of factual information on current affairs.
By presenting the facts, it is Thomson Gale’s intention
to provide its readers with everything they need to
reach an informed opinion on current issues. To that end,
there is a particular emphasis in this series on the presentation
of scientific studies, surveys, and statistics.
These data are generally presented in the form of tables,
charts, and other graphics placed within the text of each
book. Every graphic is directly referred to and carefully
explained in the text. The source of each graphic is presented
within the graphic itself. The data used in these
graphics are drawn from the most reputable and reliable
sources, in particular from the various branches of the
U.S. government and from major independent polling
organizations. Every effort has been made to secure the
most recent information available. The reader should bear
in mind that many major studies take years to conduct, and
that additional years often pass before the data from these
studies are made available to the public. Therefore, in
many cases the most recent information available in 2006
dated from 2003 or 2004. Older statistics are sometimes
presented as well if they are of particular interest and no
more recent information exists.
