Results Fifty-four reports met inclusion criteria. Data extracted thematically synthesised characteristics 58 Discussion Topic proliferating cover wide subjects. Filter reports, often clear definitions concepts scope guide users. Without standardised terminology, challenging find. Information specialists may benefit from centralised repository appraisal checklists facilitate quality assessment. Conclusion Findings will help information existing assist developers build current knowledge in field.
