Rialto enables users to upgrade the access model for Ebook Central titles directly from the License Upgrades (EBC) page (Collection Development > Market). Users can upgrade to any higher license type than the one currently owned, for example:

• 1-user license () → 3-user licenses ()
• 1-user license () → unlimited access ()
• 3-user license () → unlimited access ()

If multiple license types are owned for the same work, the lower-tier license must be upgraded first. For example, if both a 1-user and a 3-user license are held and the goal is to upgrade to unlimited access, the system requires upgrading the 1-user license first. All pricing reflects the upgrade path from the lower-tier license. 

1. Navigate to Collection Development > Market > Licenses Upgrades (EBC).
2. The page opens pre-filtered to display owned Ebook Central titles that are eligible for an upgrade. Titles with owned unlimited licenses are excluded. A query builder is available on the page to further refine the displayed titles.
