Final answer:
In the context of a university library, 'repertoire' is equivalent to B.'Catalogue', which refers to the complete, systematically ordered list of books available.
Step-by-step explanation:
The equivalent meaning of repertoire in the context of a university library's collection of books is B. Catalogue.
A repertoire usually refers to a range or collection of skills, achievements, or works that someone or something can perform or has produced.
When talking about a library, the term refers to its entire collection, which aligns with the idea of a catalogue - a complete list of items, typically one that is systematically ordered.
Since a catalogue provides the list of books available in a library, it is the term that closely resembles the concept of a repertoire in this scenario.
