Summon: More Options Link
When one or more Direct Links (IEDL) are available for a title in the search results, Summon displays the More Options link, which lists the highest ranked IEDL links per provider (selected from all calculated links). By default, a maximum of five links appear in the list. If you want to change the maximum number of links or disable this functionality, see Summon: Administration Console: Settings - Search Results.
The title-level link, Quicklinks, and unpaywall links are excluded from the More Options list.
