Establishing a uniform title is an aspect of authority control.
Anonymous works such as sacred texts and folk tales may lack an obvious title: for instance, the Bible, Epic of Gilgamesh, Beowulf, or the Chanson de Roland.
The library could also list any copies of Crime and Punishment in other media, such as film adaptations or abridged editions, under the same uniform title.
The Library of Congress provides an example of how books of the New Testament are referred to in the Anglo-American Cataloging Rules: Example:edition being cataloged: Othello / William Shakespeareestablished uniform title: Shakespeare, William ... Othellono uniform title assigned to the edition being catalogedExample:edition being cataloged: The tempest / William Shakespeareestablished uniform title: Shakespeare, William ... TempestThe complementary situation occurs with a single work that exists with more than one title, especially when translated into another language, excerpted or collected with other works.
In this case, the name of the language or a phrase such as 'Selections' is added to distinguish works with the same uniform title.
