Abstract: This study has been carried out to analyze the research field of 
high-temperature superconductivity and to demonstrate the potential of 
modern databases and search systems for generating meta-information. The 
alkaline earth (A2) rare earth (RE) cuprate high-temperature 
superconductors as a typical inorganic compound family and the 
corresponding literature were analyzed by scientometric methods. The time 
dependent overall number of articles and patents and of the publications 
related to specific compound subsets and subject categories are given. The 
data reveal a significant decrease of basic research activity in this 
research field. The A2 RE cuprate species covered by the CAS compound file 
were analyzed with respect to the occurrence of specific elements in order 
to visualize known and unknown substances and to identify characteristic 
patterns. The quaternary and quinternary cuprates were selected and the 
number of compound species as a function of specific combinations of A2 
and RE elements is given. The Cu/O and RE/A2 ratios of the quaternary 
cuprate species as a function of A2 and RE atoms are shown. In addition, 
the research landscape of the MgB2 related publications was established 
using STN AnaVist, an analysis tool recently developed by STN 
International.
