Item Editors allow you to customize the MARC record for an item without having to Toggle MARC view. You may edit the Title, Author, and Subjects for any item in your library and the new information will then be reflected on the item's MARC record. You will need to be on the Title tab of the item record in order to make these changes. You may review the Library of Congress webpage for additional information about MARC record standards.
The Title Editor allows you to view and edit the 245 Title Statement tag for the item.
The Subject Editor allows you to view, add, edit or remove subject entries for the Title. The Subject Editor is located on the Subjects tab in the Title record.
