Subject librarianship has been tense with its own set of problems which have been identified by several authors. For instance, Martin (1996) observes that there is a poor job definition or specification among subject librarians and therefore their performances are very often inadequate. Rodwell (2006: 50-51) states that subject librarians have been criticised for lacking training in subject reference work, and have to rely on trial and error as very few are given training.  Hine (2013) questions the growth of branch libraries which support subject librarianship, stating that the branch libraries are usually unplanned and lead to waste of resources and duplication of work.  Chanetsa and Ngulube (2016) are skeptical about the future of subject librarianship in an era where the communities that they serve can conduct their own literature searches on the World Wide Web.nkopyy6 Chanetsa and Ngulube extend their scepticism citing an example at the University of Bangor in Wales, where some subject librarians lost their jobs because online resources had made the search for information easier for their communities.
