After you perform a search, you will see a single list of results:
Take note...!
If you click on the link in the document title, it gives you a full view of the document, with information about the catalogue number (or numbers) and existing copies, type of loan, availability status, possibility of making a reservation request, etc..
Once you have performed the search, you can refine the results by applying different types of filters (language, availability, author, etc.) that will appear with a blue check box. You can also select which filter values you wish to be removed from the results (red check box).
They become filters that refine our searches. The inclusion and exclusion of filters can reduce the number of results and increase the relevance of them.
