Not* : The author, having gleaned the above bibliographical citations from many sources, including his own 

 not inconsiderable library, seems to have preferred to adopt the heterogeneous and individual styles of authors without 

 modification. The editors have respected this implied preference and have not subjected the Bibliography to a critical 

 styling in the interest of consistency.
