A primary mission of the Dept. of Homeland Security (DHS) is to ¿prevent terrorist attacks within the U.S., reduce the vulnerability of the U.S. to terrorism, and minimize the damage, and assist in the recovery from terrorist attacks that do occur in the U.S.¿ Since its inception, DHS has had an intelligence component to support this mission. Following a reorganization of the DHS in 2005, a strengthened Office of Intelligence and Analysis (I&A) was established. This report provides an overview of DHSI, and examines how it is organized and supports key departmental activities to include homeland security analysis and threat warning; border security; critical infrastructure protection; and sharing of info. with, state, local, and private sector partners.

Although each main-set volume of Terrorism: 1st Series contains its own volume-specific index, this comprehensive Index places all the Index info from the last fifty main-set volumes into one index volume. Furthermore, the volume-specific indexes are only subject indexes, whereas five different indexes appear within this one comprehensive index: the subject index, an index organized according to the title of the document, an index based on the name of the document's author, an index correlated to the document's year, and a subject-by-year index. This one all-encompassing Index thus provides users with multiple ways to conduct research into four years' worth of Terrorism: 1st Series volumes.
