The Institute for Scientific Information has recently released the 1998 impact factor figures for citations during 1998 to journal publications in 1997 and 1996. The figures presented in the table show that the impact factor for Thorax has risen for the second year in succession and that, of the journals dealing with respiratory medicine (as opposed to surgery),Thorax is now placed immediately below the two American Thoracic Society journals.

This continued improvement in the international rating ofThorax is a reflection of the hard work of all who are involved in producing the journal, but is ultimately dependent upon the quality of the work submitted by the researchers and reviewers who contribute to it. Thank you to all who have chosenThorax for their work. Please send us more.
