The essential cult TV reader / edited by David Lavery. (OCLC #897377307)

As this title includes a filmography separate from the rest of the bibliographical references, I included an additional note (as 504 is repeatable):

504 __ ǂa Includes bibliographical references and index.
504 __ ǂa Includes filmography.

There is also a value for this (q) in the fixed field Cont:

Cont: bq

The code ‘q’ is far down in the alphabet, and there are only four spaces in the Cont fixed field, so this code may not be always be recorded if the title has a lot of other specific contents. For example, the item was a thesis (m) which also included abstracts/summaries (a), a bibliography (b), a discography (k), and a filmography (q), the fixed field would be:

Cont: abkm
