\beginchapter Appendix I. Index

The author has tried to make this index as complete as possible, so that
people will be able to find things that are tucked away in obscure
corners of this long book. Therefore the index itself is rather long. A
short summary of the simpler aspects of \TeX\ appears at the beginning of
Appendix~B; a summary of special symbols appears at the end of Appendix~F.

\smallskip\ninepoint
Page numbers are \underbar{underlined} below when they represent the
definition or the main source of information about whatever is being
indexed. A page number is given in italics (e.g., `{\it123\/}') when
that page contains an example of how the concept in question might be used.
Sometimes both underlining and italics are appropriate.
When an index entry refers to a page containing a relevant exercise,
the answer to that exercise (in Appendix~A) might divulge further information;
an answer page is not indexed here unless it refers to a topic that isn't
included in the statement of the exercise.

Control sequence names that are preceded by an asterisk (*) in this index are
primitives of \TeX, i.e., they are built in; it may be dangerous to
redefine them.

Important works such as histories, biographies,
scientific and technical text-books, etc., should contain indexes.
Indeed, such works are scarcely to be considered complete without indexes.
\smallskip
An index is almost invariably placed at the end of a volume
and is set in smaller type than the text-matter.
Its subjects should be thoroughly alphabetized.
\smallskip
The compiling of an index is interesting work, though
some authors are apt to find it tedious and delegate the work to others.
The proofreader who undertakes it will find that it is splendid mental exercise
and brings out his latent editorial capability.

Important references are given in boldface.
Italicized numbers indicate fleeting references,
whereas numbers in parentheses refer to
mere implications or unwarranted extrapolations.
Asterisks are used to identify particularly distasteful passages.
