Letter to the Editor Available to Purchase

Dear Sir, In replying to my earlier letter, Mr Rees appears to have shifted his ground considerably. He now agrees that relevance judgements made in vivo are significantly different from those made under the conditions of the Western Reserve project—a complete reversal of the view he expressed to Aslib. Furthermore, we are now told that the project formerly described as ‘a simulated, field experimental approach’ is, in fact, an entirely empirical exercise designed merely ‘to establish certain empirical reference points with respect to relevance judgements’.
