You can batch import publication metadata to the Research Collection by uploading a BibTex or a RIS file.

Mapping Table
Mapping Table

The table below shows how the individual RIS and BibTex fields are imported and mapped into the Research Collection. Only fields mentioned in this table can be imported via the batch import process. Other fields not available in RIS or BibTex can be added later to the imported items (see Edit publications).

Format recommendation

We recommend to use the following formats when exporting publication lists from a reference management tool (the recommendation is based on the number of relevant fields exported by the tool):

  • EndNote: BibTex (exported with "RefMan")
  • Mendeley: BibTex
  • Zotero: RIS or BibTex


Select the publications you want to import in your reference management software and export them as a RIS or BibTex file (see format recommendations above) and save the file.


The next page lists all publications that could be detected within your file. For each publication, information is displayed about potential duplicates and, if applicable, invalid metadata according to the following statuses:
