We will happily try to source for you any ‘hard to find’ books, and often this might mean seeking out a pre-loved (2nd-hand copy) in ‘Good’ or ‘Very Good’ condition.
Unfortunately, many popular books are now in a status of ‘OUT OF PRINT’ which means the current publisher who owns the rights have no plans to continue printing any further editions. In this instance, unless there is a ‘PRINT ON DEMAND’ process, 2nd-hand is the only option.
