ILL and the Anglophone World

 It really is quite remarkable how often my patrons will request titles that are held in Libraries in the UK and all throughout the British Commonwealth but NOT held by ANY libraries in the United States.  Like, NONE.  Sometimes it's because the American edition hasn't been published yet, or the patron only knows the British ISBN and I have to revise my search, but other times no, there is no American edition, it's a UK and British Commonwealth Book and nobody in the USA had opted to add it to their holdings!  Still boggles my mind a little.
