Control Headings

Find out how to access and use the Control Headings window in Connexion client.

Purpose of the Control Headings window

This window opens when you use Edit > Control Headings > Single to control a heading in a bibliographic record, and the system cannot automatically control and insert it. Use the window to control a heading manually. You can:

  • View a list of matches or close matches to the heading you are trying to control.
  • Insert a proposed fully controlled heading from the list into the bibliographic record if appropriate.
    Modify the heading using the features of this window to build and insert an appropriate heading.

Access the Control Headings window

  1. With the cursor located in a controllable field of a displayed bibliographic record, click Edit > Control Headings > Single, or click Control Single Heading button, or press <F11>.
    • When a heading matches exactly and can be inserted, the client controls the heading automatically (it appears as a link), and you are finished. However, under some circumstances, the system cannot control a heading and the Control Headings window opens. For example, the window opens when:
      • An unqualified personal name heading matches (has only a subfield a).
      • No matching records are found.
      • No single authority record matches exactly, but one or more records are found that match some but not all elements of the heading.
      • Matching authority records were found for all elements of the heading, but a geographic subdivision is out of place.
  2. Click Insert Heading if the window presents an appropriate heading. The Control Headings window closes, and you are finished.
    Click Modify Heading next to a heading retrieved from the authority file to move it into the Modified Heading workspace.
    Edit the heading in the New Query box and click Match Best to do a different search for headings.

     Note: You can click a heading (link) in the list to display the authority record.

  3. (Optional) Click Append to Heading to add a subfield.
  4. Click Insert Heading after you have built an appropriate heading.

See more details about how to control headings that the system does not control automatically.
