Erratum to: Scientometrics DOI 10.1007/s11192-010-0328-z

Because of an unfortunate mistake of the typesetter the paper 11192-010-0328-z displays the wrong title.

“Self-citation: comparison between Radiology, European Radiology and Radiology for 1997–1998”

Should be replaced with:

“Self-citation in American Physiological Society Journals”
