Many thanks to Abigail and the Serials Team for this:
We will soon be making updates to the SFX GetIt! menu to improve user experience. New display logic is being put in place to limit the number of access points included in the menu. These updates will suppress duplicate access points leading to the same content on the same provider site (ex. EBSCO), as well as access points to aggregator sites where the same content is available through a preferred provider. Suppressing these access points will remove visual clutter from the menu and lower the user’s cognitive load when selecting a link to access a journal or article.
