Collection development includes the planning, selecting, and building of collections in all formats needed by the community. Collection evaluation is the continuous process of analyzing use, age, condition, timeliness, and coverage of library materials.

From Collection Management — State Library of Iowa

The IFLA School Library Guidelines 2nd edition (2015) state that a school library should be managed within a clearly structured policy framework that recognises the library as a core resource and centre for reading and inquiry. A school library policy should be devised bearing in mind the overarching policies and needs of the school and should reflect the ethos, mission, aims, and objectives, as well as the reality of the school (pp. 22-23).

In terms of the Australian Professional Standards for Teachers (AITSL, 2011) teachers working in the library have specific responsibility in terms of “policies and strategies to ensure the safe, responsible and ethical use of ICT in learning and teaching” (Standard 4.5) and to “lead colleagues in selecting, creating, and evaluating resources” (Standard 3.4).
