contributions, far beyond the call of secretarial duty, of Mrs. Violet
Lofgren and Mrs. Arlee Ellis are too numerous to list exhaustively. My
wife, Ann, also assisted in typing many drafts despite many other demands
on the time of a wife and mother. The final draft was typed by Mrs. Joan
Ippen with such accuracy that proofreading her copy was never much of a
challenge.

For permission to quote short passages from their publications, I wish
to thank Addison-Wesley, the American Statistical Association, Cambridge
University Press, Chandler Publishing Company, Charles C. Thomas,
Cornell University Press, Her Majesty's Stationery Office, Holt, Rinehart
and Winston, Inc., Human Relations, Journalism Quarterly, The Journal
Press, Meredith Press, The M.I.T. Press, The New Republic, The Observer,
Prentice-Hall, Princeton University Press, Public Opinion Quarterly, The
RAND Corporation, University of California Press, University of Chicago
Press, University of Illinois Press, University of North Carolina Press,
D. Van Nostrand Co., Western Political Quarterly, and John Wiley & Sons.
I am also grateful to the authors who permitted me to quote from their
books and articles.

The Dean's Committee at the University of British Columbia provided
financial support for preparation of this manuscript. Staff members at
Addison-Wesley solicited useful comments and suggestions from scholars
in disciplines other than my own, and they have amply demonstrated that
relations between author and publisher can be pleasant and fruitful.

Finally, my greatest debt is to someone with no interest whatever in
content analysis--the person to whom this book is affectionately dedi-
cated. His courage and good humor in the face of adversity have been a
constant source of inspiration to me.

O. R. H.
