Erratum 


The paper "A Method for On-Line Reorganization of a Database" by G. H. 
Sockut, T. A. Beavin, and C.-C. Chang that appeared in the IBM Systems 
Journal, Vol. 36, No. 3, pages 411 through 436, contained an error in 
Figure 9 on page 428. The figure above replaces the original Figure 9. In 
the original, the state represented by a box in the lower right should have 
had the label "P." In this updated version of the figure, other labels have 
been revised to improve the readability and to help the reader understand 
the accompanying text.
