ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

— Several elements have been added to handle identified use cases. As part of this SentVia has been

renamed DeliveryMethod, this element is now used in both the Request and Supplying Agency

messages. This is the only elimination of an element and has been done after consultation with

— Annex D is changed from including several use cases to one sample use case and a link to additional

— Added a RetryInfo section to SupplyingAgencyMessage, which should only be used when the Status

is RetryPossible. This section is used in conjunction with the expanded set of ReasonRetry values as

— Renamed ServiceInfo/PreferredFormat to ServiceInfo/ItemFormat and renamed DeliveryInfo/

DeliveredFormat to DeliveryInfo/ItemFormat so that we only need one Open Code list for Formats.

PhysicalAddress structure in line with the PhysicalAddress structure used in NCIP (to simplify

— For requests the element PreferredEdition has been added. In 18626:2021, the element AnyEdition

will be retained to ensure backward compatibility. In the next version of the standard AnyEdition

will be deprecated in favour of PreferredEdition. It is recommended to upgrade from AnyEdition to

This document is intended to succeed the old ISO interlibrary lending protocol (consisting of ISO 10160,

ISO 10161-1 and ISO 10161-2). Unlike its predecessor, this document 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 ISO 10160 is based on an outdated 1980s model of

ILL transactions, its successor relies on and supports a modern, much simpler ILL procedure.

ISO TC 46/SC 4 made an attempt to revise ILL standards in 2007. The chosen policy — careful revision

of the existing standard — failed, since for some SC 4 P members the revision was too radical, whereas

some other P members indicated that it was not thorough enough. In order to avoid a similar deadlock,

the SC 4 plenary meeting chose a different strategy in 2012. The committee shall keep the old standard

alive as long as necessary by, e.g. making the editorial changes needed. But SC 4 also decided to start

The new standard specifies three simple messages: a request, a supplying library message and

a requesting library message. The protocol is stateless, which means that there shall 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). Implementer experiences gathered from the previous edition

of this ILL protocol indicates that it is easier to implement than ISO 10160 and that the functionality

This document is the first part of a more general strategic initiative to standardize resource sharing in

ISO/TC46/SC4. As part of this intention, the editors have aligned element names, transport and XML

schema with similar functions in ANSI/NISO Z39.83 NISO Circulation Interchange Protocol.
