2xx Fields

2xx Introduction

2xx fields

The 20x-24x fields contain the title of the work, expression, or manifestation and the variant and former titles that apply to that manifestation. Use field 245 for the title as it appears in the prescribed source for titles for a manifestation or for a title formulated according to cataloging guidelines. The preferred/uniform title field 240 is the primary collocating title for works and expressions appearing under multiple titles, as well as distinguishing different works or expressions with identical titles. The key title field 222 is a unique identifying title for continuing resources (serials and integrating resources). Use the indicator values of these fields entered under a name access point to generate title access points and display notes.

Use the 25x-28x fields for descriptive information about the manifestation, other than title related data. This includes the edition statement, descriptive information related to specific forms of materials, as well as imprint and other publication source information and addresses.
