In principle, large amounts of data can be easily collected, structured and sorted with data processing programs such as Excel. Another option is to use literature management programs such as EndNote, Citavi or Zotero. The Saxon State and University Library Dresden (SLUB Dresden) provides an overview of current literature management programs . Software for qualitative data analysis such as NVivo is equally suited for data processing. A comprehensive overview of the features of different tools that support the SLR process can be found in Bandara et al. (2015).

When conducting an SLR, you should specify for each hit the database from which it originates and the date on which the query was made. In addition, you should always indicate how many hits you have identified in the various databases or, for example, by manual search.

Exporting data from literature databases

Exporting from literature databases is very easy. In Business Source Complete , you must first click on the “Share” button in the hit list, then “Email a link to download exported results” at the very bottom and then select the appropriate format for the respective literature program.

In the Web of Science database, you must select “Show 50 per page” at the bottom of the hit list to display 50, instead of 10, hits per page. Now select the button “Select page” at the top and then “Add to marked list” on the right. This step must be performed for all hit pages. Then select the “Marked list” button at the top left and proceed through the three steps described above. Tip: in Step 2, select “Abstract”, “Keywords”, “Research area” and “Document type”, as this information may be relevant for your evaluation.

Exporting data from the literature database EconBiz is somewhat more complex. Here you must first create a marked list and then select each hit individually and add it to the marked list. You can export only 20 hits at a time from the marked list.

After merging all hits from the various databases, duplicate entries (duplicates) are deleted.
