Foreword
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
electrotechnical standardization.
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
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see
www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 46, Information and documentation,
Subcommittee SC 4, Technical interoperability.
This third edition cancels and replaces the second edition (ISO 18626:2017), which has been technically
revised.
The main changes compared to the previous edition are as follows.
— 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
implementers.
— Annex B has been rewritten to clarify the use of open codes.
— Annex D has been changed from including several use cases to one sample use case and a has been
linked to additional use cases at the website (see Annex A).
— Annex F has been added with guidelines about the use of profiles with ISO 18626.
— Annex G has been added with guidelines about consortia.
— Annex H has been added with guidelines about handling negotiations using “retry” when the
supplier cannot fulfil the first request.
— A RetryInfo section to Supplying Agency Message has been added.
— ServiceInfo/PreferredFormat has been renamed to ServiceInfo/ItemFormat and renamed
DeliveryInfo/DeliveredFormat to DeliveryInfo/ItemFormat so that we only need one Open Code list
for Formats.
iv
— PhysicalAddress/Region has been changed from StandardCodes to free-text field to bring the
PhysicalAddress structure in line with the PhysicalAddress structure used in NCIP (to simplify
implementation).
— For requests, the element PreferredEdition has been added. For the purposes of this document, the
element AnyEdition has been retained to ensure backward compatibility.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.

Introduction
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 predecessors, 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 interlibrary loan (ILL)
procedure.
This document specifies three simple messages: a Request, a Supplying Library Message and a
Requesting Library Message. 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 provided
meets the requirements of libraries’ current ILL practices.
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 committee has aligned element names, transport and XML
[7]
schema with similar functions in ANSI/NISO Z39.83 .
In the next version of this document, AnyEdition will be deprecated in favour of PreferredEdition. It is
recommended to upgrade from AnyEdition to PreferredEdition without unnecessary delay.
For additional information about implementation of this document, see Annex A.
