摘要:I SHOULD begin this talk by admitting frankly that my knowledge of medicine and medical literature is a minus quantity. At the same time I can claim some little acquaintance with the Armed Forces Medical Library. I had an opportunity to study its problems in detail twelve years ago. Since then I have seen enough of the Library to appreciate the tremendous progress that it has made. In the past few months I have been trying to help in connection with plans for a new building and so have been a little closer to the Library than in the years just before. But I still know next to nothing of the literature included in the collections and that should be kept in mind as I talk. However, I have had a full fifty years in library work and I am inclined to believe that there is at least a family resemblance in the problems in large libraries even when they deal with subjects as different as the clinical medical sciences and the humanities.
