Ask your library if they can get it for you from another library - that is what mine would have to do
Our borough libraries all interact yes but if it’s not available in the borough (over 20 libraries) they have to buy it. Sometimes they will if requested but I have yet to convince them to buy and stock more knitting books! They carry a few and I have no idea how they chose which ones to get but I would assume the Martin Storey one I want is probably too limited in its patterns for the library to bother with. I can but ask though.
