Margarita Espinosa Library

The Margarita Espinosa Library is a hub of student activity at Castilleja.

The library’s mission is to train excellent student researchers, provide high-quality library services, and develop collections that support academics and independent reading at Castilleja. Librarians help students develop the capacity to locate, evaluate, and apply information. We create community by hosting special events and programs throughout the year such as visiting authors, an edible book festival, high tech origami, a trivia hunt, and a book swap.
