I read a lot, so i use a library. Some books come and others get lost or stuck. The stuck ones are amusing to track take my 320 page book on china that somebody in Kent still has the only copy of and for 131+ days it has remained with one person who extended that several times despite other reservations and being a short book – nobody can accuse it of being a large book at 320 pages.
The good news is that person still has it. A six month wait parhaps is taking the piss.
