In the following, an overview of SLRs in the field of economic sciences is given, with the former originating from the Business Source Complete database as well as from contacts to researchers at TU Berlin’s Faculty of Economics and Management. The order of the examples given is random.

Special features:

What is particularly good about this example is that search terms were defined by a number of experts and the review was conducted by three researchers working independently of one another. Furthermore, the search terms used have been very well extracted and the procedure of the literature selection very well described.

On the downside, the restriction to English-language literature brings the language bias into play, even though the authors consider it to be insignificant for the subject area.

Special features:

• Only very specific keywords used
• No precise information on how the review process was carried out (who reviewed articles?)
• Only journals with impact factor (publication bias)

Special features:

• Research questions are explicitly presented
• Search string very detailed
• Exact description of the review process
• 2 persons conducted the review independently of each other
