J. HE handmaiden of all modern research is 

 bibliography, and like the domestic variety it can range from 

 the heights of the superlative 'treasure' to the slatternly 

 depths of inefficiency. At its best the service it gives is incal- 

 culable, and even at its worst it is capable of some small 

 assistance. Good research work can only be built upon the 

 foundations laid by previous workers, and without the aid of 

 bibliography the student is lost. He cannot know where to 

 begin his investigations and can but grope blindly, conscious 

 of only what is immediately to hand and ignorant of all around 

 him and all that has gone before. Without bibliographical aid 

 his search for reference is inevitably imperfect and the results 

 of his investigations will reflect these imperfections."
