Herring (2007) and Purcell (2010) both realise school libraries are ‘centre[s] of learning’ (Herring, 2007, p. 27) or ‘hub[s] of the learning community’ (Purcell, 2010, p. 30). However, Purcell (2010) seems to have higher expectations; she prioritises the teacher librarian’s leadership role and emphasises multiple responsibilities, whereas Herring believes it is impossible for TLs to ‘fulfill all…roles at the same time’ (Herring, 2007, p. 31). Although teacher librarians possess the ability to fill various roles, they must refine their purpose within the school context by considering the gaps and needs within the local community (Herring, 2007, p. 31).

Lamb (2011) also highlights the importance of ‘identify[ing] priorities’ (p.31), although the requirements listed in her article are extensive. She also proposes a collaborative approach to the school library, where it is important for the teacher librarian to communicate effectively and build relationships within the school and wider community (p.29). Although other authors recognise the importance of collaboration, human connection is not outlined as a key feature of their TL models.

One commonality amongst the literature is the focus on information literacy skills. Herring (2007), Purcell (2010), Lamb (2011) and Valenza (2010) all believe TLs should be teaching students the skills they need to navigate new technologies and delivery modes. Valenza (2010) goes so far as to present a specific list of ‘nonnegotiable’ TL practices, such as the ability to create RSS feeds, blogs, websites and even Twitter posts. Unfortunately, teachers are often unable to develop students’ 21st century skills because they lack confidence and/or understanding (Purcell, 2010, p. 33) or the ‘resources, time, technical support, infrastructure and professional development’ (Lamb, 2011, p. 33), so TLs are required to provide assistance.

Academics also seem to agree that school librarians must teach students and their colleagues as part of their role. ‘School media specialists must be teachers’ (Lamb, 2011, p.35.) and should understand how to teach various individuals within the school (Purcell, 2010, p. 32).
