My favorite example of this is the famous physicist Gerard 't Hooft. His last name (by which I mean, the way you would refer to him in a formal situation like a citation) is "'t Hooft" — yes, that starts with an apostrophe and a lower-case T. However, like many names which have a prefix, it is properly alphabetized under "H", not "t" or "'". This is an example of why linguistic tagging is often necessary, not just nice-to-have. A Dutch author "van Dijk" should be sorted under D, but an American (or, perhaps, Belgian) author "Van Dyke" should be sorted under V. The same is traditionally true of Scottish names starting with Mc/Mac, as I understand it. The rigid FIRSTNAME LASTNAME model of human names breaks down in very, very many places.
