We would like to refer to the recent article of Banerjee and Williams [1] which is a topic of great interest to many researchers. The authors studied the effect of shear deformation on the elastic buckling load of columns. On page 608 of their paper, it was stated that ''. . . a literature survey on the subject of... buckling analysis of columns reveals that when considering this (shear deformation) effect... only very limited results have been published: e.g., results for a cantilever column''. On the contrary, there are many readily available papers on this area containing abundant buckling results. These papers [2-18], which are arranged in a chronological order, are given in the references here. Of the many cited papers, we would like to draw the authors' attention the paper by Ziegler [3]. In his paper, Ziegler derived the relationship between the Engesser critical load and the corresponding Euler critical load which was presented as equation ( 17) in the author's paper. Where the relationship does not hold, as for the case of the clamped-hinged column, he has derived the exact solution and proposed a slightly modified form of the relationship for accurate results: that is,
