You can get complete information, including costs, for Knogo strips from John
Whiteman.  He can be reached via voice mail, he is good about returning calls,
at 800-255-1563, x5438.  They have different types (media) of strips and
different lengths of strips designed for books.  I believe the shorter strips,
which will be detected by the newer 3M systems cost about 4 cents in quantity.
