The location of the music collection is affected by the purpose for which it is maintained. A collection for scholars alone should certainly be in a separate room, with an expert custodian. But when we regard the collection as a means of popularizing music and of improving popular musical taste, the matter takes on another aspect. A person who comes to the library for the purpose of visiting the music room will find it, no matter where it may be, but the reader who needs to have his attention called to it or in whose case it must compete for use with other books, will never do so. Going back to our analogy with general literature we may note that when a librarian wishes to promote the circulation of some special class of literature or call attention to some particular book or books, the last thing he would think of doing would be to set them apart in a special room. What he does do is to place them conspicuously in the most frequented spot in his library. This is, of course, only one side of the question. No one can browse in a collection of books unless he knows how to read; and so long as music readers can not read “to themselves”, the reading of instrumental pieces can not be done without the aid of the actual instrument. Even when one can read music to himself well enough to pick out what he wants it may aid him to be able to perform the piece on the instrument for which it was written. Now the most frequented spot in the library, where I recommend that the music collection shall be displayed, is not the place for a piano or for its use. This must necessarily be in a separate room. These are not, however, absolutely irreconcilable requirements. It is not necessary that the music and the instrument should be in the same room. A sound-proof or a distantly-located room, for the instruments, may be used by those who wish to perform pieces before selecting them, even if no music at all is shelved in the room. This room should preferably be as near as possible to the music shelves, and if it is it must of course be sound proof. Going back again for a moment to our analogy, the provision of a sound proof music room corresponds to the creation of a similar room for the ordinary reader, where he may take his books and read them aloud to see how they sound. The mere statement shows us how far behind our ability to read language is our ability to read music.
