=201.= None of the foregoing recommendations for discarding, except the last, applies to bibliographical rarities or curiosities; to works of recognized literary merit which are mentioned in histories of literature; to books which are of local interest; or to special collections. They apply simply and solely to the rank and file of literature, the 50 per cent. of the fruits of the press which become stale through effluxion of time. The question of how to dispose of discarded books can generally be decided by some local circumstance. Discarded text-books of science are generally of little value to anyone, and need not be preserved at all. But faded works of travel, history and biography may find interested readers in workhouses, hospitals and prisons. To these, or similar institutions, the discarded books of a public library could be transferred. It is hardly necessary to point out that books which are not good enough or fresh enough for a central library, are not good enough for a branch library. Books proposed to be withdrawn permanently should be submitted to the library committee, and lists of the discarded books may be printed in the bulletin, if there is one, or, failing that, in a separate form. It is useful that readers likely to be interested should be afforded an opportunity of judging the proposals and action of the library committee in its work of weeding out the library. Any serious objection to a book being removed should be considered, and nothing should be done without the utmost deliberation, because, as yet, we have not achieved a public library _index expurgatorius_ of books not worth preserving. When this comes, the task will be immensely lightened. Books which are discarded should not be permitted to leave the library unless stamped, to indicate that they are rejected. A stamp with a movable dating centre should be used, with the words, “Public Library, Discarded,” in a circle.
