Concepts don’t include all expected results

Observation: For example, a search for “genealogy periodicals” in Concept brings up no results at Adriance, despite the fact that they have many materials classified as such in Sierra.

It appears that the concept Genealogy–Periodicals only includes resources with that exact subject heading in Sierra and not those with “genealogy periodicals” as parts of a subdivision, such as “United States — Genealogy — Periodicals” or “New York (State) — Genealogy — Periodicals — Indexes.” Searching by keyword (All) instead of Concept provides some more results, but not as many as in Encore.

Improvements to the Concepts feature are needed in order to better capture the items that would reasonably be considered to be part of a concept, especially in regard to subject heading subdivisions and related subject headings for Concepts that are based on traditional library subject headings.

Status: MHLS will report the issue to Innovative and push for improvements to Concepts.

Resolution: TBD.

The concept in Vega contains 14 resources
A subject search in Encore for the same term returns 65 resources
