MathSciNet’s Help function describes Collaboration Distance as follows:
‘An interest in the ‘distance’ between people has been popularized in both the mathematical community (Erdös numbers) and the general public (Six Degrees of Separation). In mathematical terms, this can be thought of in terms of the collaboration graph: the graph with authors of mathematical papers as vertices and edges connecting authors who have been co-authors on at least one paper. The MathSciNet database provides an example of a relatively large collaboration graph. The distance between two authors is defined to be the length of the minimal path (if a path exists) between the two authors in the collaboration graph. A search returns one of the minimal paths from the first author to the second author. It displays each edge in the path: each co-authored paper. For each edge it is possible to find all the papers authored by each author, as well as all the papers co-authored by the two authors’.
Enter the names of the authors for whom you wish to know the collaboration distance and click Search. Use Erdös is a reference to Paul Erdös (The Erdős number, named after the Hungarian mathematician Paul Erdős, is a way of describing the ‘collaboration distance’ in scientific articles between an author and Paul Erdős.

In our example you see a collaboration Distance (4) between Joseph Steenbrink and Klaas Landsman, both working at Radboud University.
