Routing Table Overview

The Routing Table is the grouped list of institutions to which your serial requests will route, if the library meets the other routing instructions for a request (holdings, delivery method, service level, EFTS, and color copy). Individual libraries and Library Groups to which the library belongs can be added to a Routing Table.  The institutions and Library Groups listed are a library's primary lending partners.

 

The Routing Table is comprised of nine (9) cells, each of which can contain up to twenty (20) libraries or Library Groups (a Library Group takes up one position in a cell).  The order of routing is sequential from Cell 1 through Cell 9. All libraries within a cell are evaluated for routing a request before the routing algorithm moves to the next cell of libraries.  Individual libraries and libraries in a Library Group within the same cell are treated equally by the routing algorithm in terms of the ordering of routing.  Routing within a cell is random to provide a degree of load balancing. Since routing within a cell is random, institutions are displayed in alphabetical order in the Routing Table. There is no "position" within a cell which determines routing order.

 

The Workspace is a holding area for institutions being added or moved as libraries work on modifying their Routing Table over a period of time. DOCLINE populates the Workspace with any Library Group to which the library belongs.  The Workspace is automatically updated with any library group membership changes.

 

Strategies for setting up Routing Tables vary from region to region. Your regional DOCLINE coordinator can provide valuable guidance for managing your Routing Table.  For more information on how to best organize your Routing Tables, contact your DOCLINE Coordinator at 1-800-338-7657 in the US or at 1-800-668-1222 in Canada.

 

Typically, libraries structure their Routing Table so that preferred low cost lenders are in lower numbered cells, followed by preferred lenders with higher costs.  Preferred lenders could be based upon good service and/or low cost, or part of a library group or reciprocal agreement.  Some libraries also include regional preferences in their Routing Table organization - libraries in their state or region in lower numbered cells, followed by other libraries in higher numbered cells.  Libraries can also establish east and west coast cells if they regularly order rush requests and want DOCLINE to first attempt to route to a particular geographic region.  These geographic cells could be selected and deselected as needed.
