Cover information indicates that the book includes over 2,600 entries. Entries are fairly clear with good cross-referencing when appropriate. An asterisk is used to indicate references to topics covered elsewhere. References have been provided which document the history and latest developments in the field. Initialisms and acronyms are abundant in this area and are covered nicely.
Entries make it clear when there is more than one meaning for an acronym or initialism.
They also indicate what the letters stand for. There are not always cross-references or entries from the full name however. While this would likely increase the number of entries, it would be helpful. Instructions on the dictionary, such as what the asterisk means, could be clearer. They are listed as almost an after thought in the introductions.
