In Relais ILL the search for possible locations to fill a request (either from your own collection or from another library) is done using Search Auto and Search Manual.
Each instance of Search Auto and Search Manual specifies which catalogues are searched. In Search Manual, each of the catalogues displays in separate tabs in the Results Details area. For Search Auto, these are the selected catalogues that are searched automatically.
Note: Each related instance of Search Auto and Search Manual must have catalogs in the same order to ensure Search Auto results display for the correct catalog tab when viewed within Search Manual. For example, if you have Search Auto - Requesting Articles configured to search your home library and AMICUS, then the same catalogs must be configured for Search Manual - Requesting, and in the same order. Note in Search Manual, it is possible to configure additional catalogs after the ones used in Search Auto, e.g., WorldCat.
