Where can I find information about the library of my campus?

Almost all the libraries that belong to the ULL have their own blog where you can find the library hours, services, stuff contact,  new items, recommended bibliography...Also you will find a wide variety of news related to the study field of each centre. You can access to these blogs with this link:
http://www.ull.es/view/institucional/bbtk/blogs/es.
You can also find information about your library in the library's homepage: http://www.ull.es/view/institucional/bbtk/Bibliotecas_y_fondos_1/es

How do I find recommended bibliography from the library?

You have two different options:

You have to click   Recommended Bibliographies, at the right side 
menu of the Catalogue.
                                                       

Or, in The library's blog of your faculty,  in the tabs "Recommended
Bibliography" or "Recommended Books by Subjects ".
