Subject Enrichment

The Subject Heading Updates Enhancement contains several different options for adding or updating Subject Headings, one of which is Subject Enrichment.

Subject Enrichment searches records for existing terms and adds or replaces those terms with new ones. Mitinet™ has lists of existing terms to run as provided (such as Kid friendly terms), and individual list items can be customized. User-created lists are also supported.

Options for Subject Enrichment are stored in your Profile. Click on the Profile link at the top of the page or select the My Records > Options > Profile Settings menu item.

Within the Profile, go to the Enhancements tab and scroll down to Subject Heading Updates > Subject Enrichment

A checkbox displays to the left of each group containing items. Check the group to perform updates for that group. The number in parenthesis contains the number of subject enrichment items that are turned on in that group.

BestMARC contains default groups, such as Kid friendly, which adds kid friendly subjects based on official headings, such as adding "Spiders" when "Arachnids" is found.
