      abstract     = {Isotope shifts have emerged as a sensitive probe of new
                      bosons that couple to electrons and neutrons, and of nuclear
                      structure. The recent Hz- or even sub-Hz-level isotope shift
                      measurements across different elements call for a global
                      assessment of all available data. In this work, we present
                      the fit framework $\kifit$ that for the first time enables a
                      combined analysis of isotope shift data from several
                      elements, taking into account correlations. We provide a
                      thorough comparison of analytical methods and the fit to
                      analyse linear and nonlinear King plots and quantify their
                      uncertainties. Finally, we provide recommendations for
                      future measurements that could enhance the sensitivity to
                      new physics and offer new insights into nuclear structure.},
