"Cheap good books -- and next comes the problem of how to hear of them -- so that we may -- from the ends of the earth -- order the ones we really want and spend our sixpences properly. Well, probably half my hearers have never heard of what is called documentation, and they think bibliography is something remote and scholastic and all that sort of thing. But really it is nothing more or less than indexing all that has been written in the world, so that you can find out quickly and surely what has been done, by whom, and under what title. Don't you want to know that? And do you know it? There are hundreds of clever people working out methods of indexing and in a little while it will be quite possible to print and keep up-to-date bibliographies, lists of all the best books, in every great group of subjects in the world. It would be as easy to keep up such bibliography as it is to keep up the issue of railway time-tables. The cost of producing these book guides need not be very much greater than the cost of producing those time-tables. I doubt if today a hundred thousand of us use any bibliographies at all. What is the good of reading unless you know what books to read? Bibliographies ought to lie about in every educated household. (pp. 191-2)"
