  2. Evaluate Information: Rationale • Why users should evaluate information and sources?: • It is a way of validating information obtained in order to prove the credibility of the evidence obtained • It ensures the extent to which the information obtained is relevant to the problem or research topic • It determines the nature of information obtained (is it a piece of evidence, opinion or propaganda) • Libraries & other information institutions have developed various evaluation criteria. Evaluation of information and sources considers both, print and non print sources (such as Internet sources).

  3. Evaluate Information: Rationale • The evaluation process may be carried out based on: • Reviewing the information need with the information found • Reviewing the bibliographic information of the source found to determine how useful the information will be in relation to the topic or research problem • Reviewing and evaluate printed sources list.
