About the Insights Builder

Allows users to perform detailed collection comparisons at the individual and group level in Choreo Insights.


Using the Insights Builder, you can make collection comparisons between two groups: The My Libraries (A) group, which consists of one or more holding symbols from your institution, and the Comparator (B) group, which consists of holding symbols from libraries or lists that you choose to compare to.

To learn how to run a report of your query, see Run a query.


1. Analysis Type

Compare your collection (Group A) to the collections of other libraries (Group B) using one of four different analysis queries.

All Show titles held by either Group A OR Group B
Overlap Show Titles held by Group A AND Group B
Distinct Show Titles held only by your library or group (Group A)
Gap Show titles held only by your comparator libraries (Group B)

2. Groups

My Libraries (A)

Your My Library group will be automatically configured when your Choreo Insights account is initially set up. This group is configured based on your institution's WorldCat holdings symbol(s).

Comparator Groups (B)

Comparator groups are created by selecting other libraries' collections from a list on the Comparator Group page.

3. Lists

Upload custom-created title lists and compare them against your institution's collection. These title lists can be uploaded by anyone from your library as long as they have a Choreo Insights account. For more information, see Create a title list and Upload a title list.

4. Query Filters

Filter name Details
Subject Classifications

By default, the report will query All Subjects. Use the slider to switch between LC and Dewey subject classifications. Selecting LC will allow you to filter by Specific LC Classes. Selecting Dewey will allow you to filter by Specific Dewey Ranges

If you have chosen to filter by specific classes or ranges, use the accordion buttons to expand them for more granular filtering options.

The query filters clear every time you switch between classifications.

FAST Heading

Use FAST subject headings to look at specific topics. To use FAST subject headings:

  1. Choose to limit the search by selecting from the following Facets:
    • All
    • Personal Name
    • Corporate Name
    • Meeting
    • Uniform Title
    • Event
    • Chronological
    • Topical (default)
    • Geographic
    • Form / Genre
  2. Search for the appropriate headings using the search box:
    Search type Details
    Phrase Search Provides a broader search across FAST facets. Click ADD after typing in a phrase search to add it to the Active Filters and continue adding phrases.
    Heading Selector Provides the ability to be more granular in applying FAST headings to the search.
  3. Select those you wish to add to your search.

If necessary, adjust the rows per page to show longer lists of matching terms.

FAST (Faceted Application of Subject Terminology) is derived from the Library of Congress Subject Headings (LCSH) and is one of the library domains' most widely used subject terminology schemas. The development of FAST has been a collaboration of OCLC Research and the Library of Congress. Work on FAST began in late 1998.
