ISO 18626 Information and documentation - Interlibrary Loan Transactions succeeds ISO 10160, ISO 10161-1 and ISO 10161-2. Unlike its predecessor, ISO 18626 is well suited to the modern, Web-based technological environment which is based on XML and Web services. Another important difference between the two standards is that while the old standard is based on a 1980s model of ILL transactions, its successor is based on and supports much simpler exchange of transactions.

The standard includes three simple messages: a request, a supplying library message and a requesting library message and confirmations messages for this. The protocol is stateless, which means that there will be no need to maintain the interconnected state tables in the client and server applications (and the connections to the state tables in applications behind them). It is expected that the new ILL protocol will be much easier to implement than the old one, while still retaining the essential functionality of its predecessor.

ISO 18626 is the first part of a more general strategic initiative to standardize resource sharing in ISO/TC46/SC4 Technical Interoperability.

CILLT (Centre for ILL Transactions) supports the implementation of ISO 18626 and maintains this website. For more information about CILLT including how to become a member please visit: http://illtransactions.org/cillt.html

Errors with the XML for ISO 18626:2021 have been reported and so a new version is required and has been posted to http://illtransactions.org/schemas/

In summary:
1. An error in the definition of ServiceType has been corrected.
2. In the previous version of the standard all three messages (Request, SupplyingAgencyMessage and RequestingAgencyMessage) had identical header fields, and this was reflected in the XSD by having a single header definition that was used for all three messages. However in the 2021 version of the standard, subtle differences between headers were introduced and so the XSD has had to be modified to define a distinct header structure for each message's "header" element.

The creation of a Category A liaison between CILTT and ISO TC 46 Information and Documentation – SC4 Technical Interoperability has been unanimously approved by ISO. This ensures CILLT will provide ongoing communication between the body responsible for ISO 18626 and the ILL community.

March 3, 2022

The CILLT Editorial Committee has sent an application for creation of a Category A liaison between CILLT and ISO TC46 Information and Documentation – SC4 Technical Interoperability to ensure ongoing communication between the body responsible for ISO 18626 and the ILL community. The ISO Central Secretariat has responded and will handle the application.

January 19, 2022

After the publication of ISO18626:2021 in December 2021, CILLT is moving from being an interim organization and is starting the application process to become a category A liaison to ISO TC46/SC4 Technical Interoperability. A ballot of all CILLT members resulted in unanimous agreement to remove Article VIII regarding the Interim Organization, from the CILLT statutes.

The next step is to send the application for a Category A liaison to ISO.
