For example: “info:bibframe\publisherNumber\ 256A090”. This is the case the worries me. For example there is an important local identifier here called "Books in Māori" / "BIM" Based on a recent print work: http://books.google.co.nz/books/?id=oAUWAQAAIAAJ To the best of my knowledge there is no digital edition of the work and unlikely to be an economic market for one.
