Fallback Record Loaders
This feature was introduced in VuFind 5.1.
This very specialized feature is used by VuFind's record loader. When records fail to load in the normal way, fallback loaders can be run to try to retrieve records by other means. For example, a Summon-specific loader is provided which can use bookmark information stored in VuFind's database to relocate records after their IDs have changed.
