Regarding my comments about QRS using Scotch brand adhesive tape for
repairs.  Some people have written me saying that it's not a problem
to use this product.

I went to the 3M web site to see what I could find, and they do
advertise that it'll remain invisible over time.  I guess it might
remain invisible, but I cringe at the rare rolls I have that are
covered in yellow, petrified cellophane tape, whose removal requires
acetone and other chemicals that I'd rather not touch.  I'm not so
sure how Scotch Magic Tape will behave 30 years from now.

This is an excerpt from the 3m Magic Tape product information page:

  "Scotch(TM) Magic(TM) Tape -- Mend it, seal it and secure it with
  this permanent transparent tape.  Non-yellowing tape disappears
  when applied, and stays invisible over time.  Can be written on.
  Available in a variety of lengths, widths and core sizes.
  Refillable dispensers also available. "
