Hi there - in the course of "talking by Email" to various KN players that I have "met" through this forum I have mentioned that I "borrow" music sheets/scores from my local library.
More than one of these players has mentioned that it had never occurred to them to see if their library had a sheet music section.
My local library is part of the Hampshire Country Library service and on-line, I can look at their catalogue to see if there is a particular book in any of the 100 or so branch libraries in the county. I have recently been able to track down a book that is now out of print, reserve it, and had it sent to my local library so that I could borrow it.
Worth a try if you are after a particular melody - how often have you looked at a musicbook of 20 or so songs and you have most of them already? Joan
