There can be a small positive side to this.  I recently looked for
period books on playing piano rolls.  To my surprise, 'The art of the
Player Piano' (Grew) and 'How to use a Player Piano' (Ellingham) both
came up on Amazon Market place from second-hand booksellers, and they
cost me a few pounds each.  They had been withdrawn from public
libraries in Leeds and Maidstone where they lay un-read for years.
