s are both the librarians and the library users, meaning that the study does not seek to obtain a sample from an unknown general population, which would in turn require that the sample is generalized to represent the entire population (McCabe, 2005).
While the challenges facing funding and sustainability of library service is a common challenge for different libraries in different states, each library has its own unique challenges, which may not be generalized. Therefore, the aim of the study is not to obtain a representative sample of the population, but a sample that is unique to the Clayton County Library System (CCLS), in terms of exposure, usage and experiences. This is because; it is only such a sample that would be in a position to give both comprehensive and reliable information regarding the library. Thus, instead of seeking to have a sample population that can be inferred to represent the general population, the main target of the study is to delve into the intricacies of the experiences of the librarians and the library users, as a means of reaching an informed conclusion regarding the sustainability of Clayton County Library, so that a diversified structure of funding can then be recommended, based on this information. Therefore, since the study is neither seeking a representative sample nor targeting generalization, the application of the purposive sampling strategy under non-probability sampling method is recommended for the study.
The selection of a representative sample for this study is important, to ensure that the information gathered through the interviewing process is not biased. However, this is a secondary requirement as far as this study is concerned, considering that the main objective of the case study is to obtain as detailed information as possible, regarding the experiences of both the librarians and the library users. Obtaining experiences does not pose any major risk of biases, considering that sensitive information regarding the
