Libraries in international schools, including XLIS, play an important role. They enhance learning across the school community. The librarian, besides the overall management of the library, is responsible for the collection development. This includes not just books but virtual/digital sources of information as well. The librarian collaborates with teachers to build a collection that supports the concepts taught in the classroom.
They provide services that aid and support learning and teaching. They play an important role during the PYP Exhibition, MYP Personal Project, and DP Extended Essay, by acting as mentors and educating students on academic honesty, plagiarism as well as citation techniques. The school library plays an important role in furthering the objectives of the school.
