Data Transfer Protocol Between Library Automation Devices and Automated
Circulation Systems
Introduction
This protocol provides a standard interface between a library’s Automated Circulation System (ACS) and library automation devices. The protocol was developed originally as an interface between the Automated Circulation System and 3M™ SelfCheck™ system. With the growth of automation in the library, there is an incread need for a standard protocol.
This standard protocol will be applicable to ACS system interfaces to automated devices and rvices where patron information and/or library material information is required.
This standard protocol benefits the library by enabling them to:
•Add new types of automated devices and rvices to the library with minimal change to the ACS system.
•Upgrade to new versions of automated devices with minimal or no change needed in the ACS system.•Change from one ACS to another without the need to replace equipment or rvices that interface with the ACS.
T his standard protocol description will be uful to:
•Vendors of library systems and devices who wish to develop a standard interface between the ACS
and automated library devices.
•Library planning committees who are planning new types of automated devices and rvices for patrons or staff.

W hat’s New with the Standard Interchange Protocol?
T his document describes Version 2.00 of the 3M Standard Interchange Protocol. Version 2.00 builds on top of Version 1.00 of the protocol, adding new messages, and new fields to already-existing messages. All new messages and fields are indicated by having “2.00”in front of them in the
message definitions. Any messages and fields that are not prefixed by “2.00”existed in earlier versions of the protocol.
