Yes, that is weird. I'm trying to figure out where it is coming from. In a few cases I've seen like the one I posted, it appears they are multiple editions of the same book, in which case the cataloguer probably duplicated the record. I haven't tested this theory out, but I could see where it might just add in another biblionumber to the string already there.
