Editing Authority control (section)

===Same name describes two different subjects===
Sometimes two different authors have been published under the same name.<ref name=tws2NovYfuf/> This can happen if there is a title which is identical to another title or to a collective uniform title.<ref name=tws2NovYfuf/> This, too, can cause confusion. Different authors can be distinguished correctly from each other by, for example, adding a middle initial to one of the names; in addition, other information can be added to one entry to clarify the subject, such as birth year, death year, range of active years such as 1918–1965 when the person [[Floruit|flourished]], or a brief descriptive epithet. When catalogers come across different subjects with similar or identical headings, they can [[Word-sense disambiguation|disambiguate]] them using authority control.
