Mr. ILES: We expect that this bibliography of Mr. Larned's, and any others in the same series which may follow, will appear also in card form, and I very much desire when the central bureau finds that a particular note can be replaced by a better one, in the light of further developments, that that particular note should be withdrawn, and a better and more nearly just note be substituted; all gratuitously to the subscribing libraries. F. M. CRUNDEN: I realize the force of what Dr. Ely has said, but I still believe that this work is worth doing, because it is exceedingly valuable to us. We have got to have some guide. We cannot all of us read in all lines and so far as the contradictory notes referred to go, it seems to me that all that was necessary was for the editor to apply to those two divergent notes just the remark that Mr. Thwaites made--that one was written from the standpoint of the sociologist and economist, the other from that of the historian and geographer. From one side it was a good book; from the other side a bad book. Mr. PUTNAM: I speak on such a subject as this with very great reluctance, and yet, as a librarian who has had occasion in times past to select--I do not have so much occasion now, because so much matter comes to us without inspection--I wish to draw a distinction between selection and exclusion. Now, when Dr. Ely speaks of an _index librorum prohibitorum_ or an _index expurgatorius_, the implication is that the libraries of this country, on advice or of their own motion without advice, are deliberately excluding from their collection books of which they disapprove. The librarian, however, approaches the matter in an entirely different way. He has at his disposal, for purchase, a very limited sum of money; a very limited sum of money, no matter how large his library, for the amount of literature put upon the market is practically limitless. Men of science themselves, after contending for liberty of expression, do not always use that liberty with discretion or to the advantage of the community. Now, there must be a selection. That is the point we start from as librarians; that is the duty laid upon us--to get, with the means at our command, the books that will be most useful to our constituents. Now, that means choice. How are we to make a choice? I do not believe there is a librarian in the United States who would set himself up as an arbiter or an expert in every department of literature; who would claim to determine the value of doctrine, either in religion or in economics, the two departments of literature as to which the discrimination must be most difficult and most dangerous; and yet even in those departments we must choose. That means a selection. What is the alternative, in case we have no guide? What would Dr. Ely offer us? Dr. Ely, of course, as any university professor, has his students, who are studying not merely one subject in which they wish to
