The titles listed under a particular month reflect the anticipated street date of publication.  Due to the nature of the publishing world, publishing dates are frequently postponed, titles are changed and books are even cancelled by the publisher indefinitely. Once the library places an order for a new book, a brief record is created in our catalog which then allows holds to be placed. If the brief record cannot be found it usually means that it is too early for us to place an order. Please check the catalog again closer to the publishing date for availability
