A user performs a keyword search. It fails. Why? Because the word was misspelled in the database.Somebody browsing the shelves of a library by Dewey class number doesn't find what they want because thework is misshelved, not because the shelver didn't pay attention, but because of a wrong number in the record.Someone looks for somebody by a personal name heading and they find not only works by the person theywere looking for but also others with whom that person was confused because they share the same heading, orbecause a heading has actually been wrongly assigned. Or in another case, a new heading has been sincecreated to which that person should have been moved. A scholar searching for works published in abibliographic series finds some of the works in that series, concludes he’s found them all, but is wrong: thereare others he didn't know about because no access to those other works is provided by a series heading.
