In the present climate of fascination with online this and digital that, it is easy to lose sight of the importance of the monographic collection in the evaluation of any library's ability to serve its clientele. Within realistic budgetary constraints, this collection should be maintained in a fashion as recent, relevant, accessible, and comprehensive as possible. In this regard, as in so many, there is striking variation between libraries, and even between subject fields in a given library. This article presents the concept of the "Gift Horse Collection Development Plan," a weeding technique in which a librarian in charge of collection development targets an approximate number of volumes to be weeded from each subject area, and the librarian in charge of that subject area considers each book as though it were a gift. If the book would not be accepted as a gift, it should not be kept. The author advocates that a typical library's clientele would be better served by a collection with somewhat fewer books, roomier shelves, and higher standards for inclusion.
