As already stated in section 52, names with prefixes are taken as part of the name, and arranged accordingly. If the prefix is abbreviated as M’, or Mc, or St., it is placed in order as if spelled out Mac or Saint. This does not imply that the name must be so altered in the catalogue, and refers to the order only. Names like Müller should be arranged as Muller, taking care that other entries are not under Mueller, but this is a matter that can be best dealt with according to the circumstances of the case, as, for instance, Goethe should be so alphabetised, and not as Göthe. Diphthongs are alphabetised as separate letters.

115.—Abbreviated words in title-entries are also treated as if given in full, and consequently “Dr. Thorne” and “Mr. Isaacs” do not come immediately before “Drab” and “Mud,” but with “Doctor” and “Mister” respectively. It need hardly be said that “Mrs. Bligh” or any other Mrs. is not alphabetised in either the abbreviated or colloquial form, but as “Mistress,” and therefore does not come between “Mozley” and “Muddock.” Other abbreviated words are arranged upon the same plan. “Fo’c’s’le yarns” appearing as “Forecastle,” though the exception to this rule is found in other elisions contained in such entries, as
