MARC Record Input Standards

To be accepted into the Iowa Locator database, a MARC record must contain the following fields and elements when they are included on the item.

MARC Fields and Subfields Example
Leader Field
Each MARC record must begin with a leader 24 characters long. All characters must be alphanumeric, special characters like ',' are not valid leader characters.  If an electronic record does not contain a leader, it is essentially not a MARC record. The leader field contains important information about the type of record, bibliographic level and the format of the item. Purchased MARC records should always contain a leader. Library automation software will automatically create a leader field. It is important to choose the correct template (e.g. book, video, kit) from the cataloging software when creating new records for the library’s own catalog or Iowa Locator, as this will determine the proper leader field.
