Identify appropriate methodology, instrument and data analysis procedures
A review of the literature helps the researcher to identify what research approaches and
methods have or have not been tried and to determine what data gathering instruments
already exist. Review of earlier research provides insight into a variety of research methods
used and enables the
researcher to select a method, design
an appropriate research
instrument and develop a data analysis strategy.
Moreover, reviewing the literature provides clues to factors that influenced the method and
instrumentation of earlier research and explains how the research was carried out. Lastly, a
review of the literature assists the researcher with the conceptual and operational definition
of the key terms, assumptions, limitations and the articulation of research questions and
hypotheses of the new research project.
Demonstrate theoretical and conceptual gaps in the field
It is critical for the researcher to understand how earlier research helps to guide and inform
their own study.
Therefore, the literature review must not only improve the researcher’s
knowledge of the chosen field but also demonstrate the depth of understanding of the field.
Table 2.1 below provides lists of the different types of literature sources available when
conducting research.

Strategies for literature review
• Structure the literature review as early as possible in terms
of headings and sub-
headings; these can always be revised and amended as time goes on.
• Draw concept maps.
• Write as much as possible about aspects of the research area; writing can always be
restricted later.
• Formulate questions that the literature review addresses.
• Read through the theses or assignments written by previous researchers and examine
their literature review chapter.
• Search indexing and abstract databases.
The scope of the literature review is illustrated in Mind map 3.2 below.
