Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member
bodies). The work of preparing International Standards is normally carried out through IS0 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. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical
standardization.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication
as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
International Standard IS0 10 16 1- 1 was prepared by Technical Committee ISO/TC 46, Information and Documentation,
Subcommittee SC 4, Computer applications in information and documentation.
This second edition cancels and replaces the first edition (IS0 10 16 l-l : 1993), which has been technically revised. It includes
amendments specified in IS0 10161, DAM 1 and the corrections specified in Defect Reports l-23.
IS0 10 16 1 consists of the following parts, under the general title Information and documentation - open Systems
Interconnection - Interlibrary Loan Application Protocol Specification:
Part I: Protocol specification
Part 2: Protocol implementation conformance statement (PICS) proforma
Annexes A to D form an integral part of this part of IS0 1016 1. Annexes E to H are for information only.

Introduction
This part of IS0 10 16 1 is one of a set of International Standards produced to facilitate the interconnection of computer systems.
It is related to other International Standards in the set as defined by the Reference Model for Open Systems Interconnection
(IS0 7498). The Reference Model subdivides the area of standardization for interconnection into a series of layers of
specification, each of manageable size.
The aim of Open Systems Interconnection is to allow, with a minimum of technical agreement outside the interconnection
standards, the interconnection of computer systems:
a. from different manufacturers,
b. under different managements,
c. of different levels of complexity,
d. of different ages.
This part of IS0 10 16 1 provides a protocol specification for Interlibrary Loan (ILL) communication. The ILL protocol operates
in the Application Layer and allows the parties involved in an ILL-transaction to progress through the ILL-transaction in an
orderly and defined way.
The ILL protocol has been designed to support the ILL services defined in IS0 10 160, the ILL Application Service Definition,
which generally requires invocation of external delivery services to fulfill an ILL request. The ILL protocol carries information
that permits both automatic and operator-mediated invocation of external delivery services.
This part of IS0 10 16 1 is one of a number of related standards supporting the interconnection of library systems. These
standards can be used by themselves or in a cooperative manner to support library applications requiring a mixture of
communications services. For example, IS0 23950, which supports remote access to bibliographic databases, could be used in
conjunction with the ILL protocol to obtain item identification information. The control and management of interactions among
such bibliographic applications are local matters that are outside the scope of this International Standard.
Security and accounting issues as they relate to ILL operations are for further study.
The specification technique used in this part of IS0 1016 1 is consistent with techniques used in defining other OS1 protocols.
Within most of this document, the technique is self-explanatory. The Abstract Syntax of the ILL Application Protocol Data
Units (APDUs) is defined by means of the ASN.l specification technique specified in ISO/IEC 8824.
This part of IS0 1016 1 contains eight annexes. Annexes A to D are normative. Annex A specifies the the state tables for the
ILL protocol. Annex B specifies the encoding rules for generating a transfer syntax compatible with EDIFACT as defined in
IS0 9735. Annex C specifies the object identifiers assigned in this part of IS0 10 16 1 and registration requirements. Annex D
defines the registration procedures for ILL EXTERNAL data type definitions. Annex E is an example of an ILL EXTERNAL
data type registry entry. Annex F describes the possible mappings of this protocol onto supporting services. Annex G describes
possible methods of using a document delivery protocol in conjunction with the ILL protocol. Annex H is a bibliography.

- Part 1: Protocol specification
Protocol Specification
1 Scope
This part of IS0 10 16 1 defines the protocol for an ILL application-service-element (ASE). It specifies the behaviour which
must be exhibited by a system in order to take part in the provision of the IS0 interlibrary loan service.
It provides a formal statement of the rules of behaviour of each of the two or more entities participating in an ILL transaction. It
specifies:
a. the actions to be taken on receiving request service primitives issued by an ILL service-user;
b. the actions to be taken on receiving application-protocol-data-units (APDUs);
c. the actions to be taken as a result of events within the local system.
It provides a specification (in clause 9) of the abstract syntax required to convey the ILL protocol APDUs.
It states the conformance requirements to be met by implementors of this protocol (in clause 10).
The scope of the ILL protocol is restricted to the interconnection of systems; it does not specify or restrict the possible
implementation of interfaces within a computer system. Computer systems may range from stand-alone workstations to
mainframes.
This part of IS0 10 16 1 is intended for use by libraries, information utilities such as union catalogue centres, and any other
system which processes bibliographic information. These systems may participate in an interlibrary loan transaction in the role
of requester (i.e. an initiator of ILL requests), responder (i.e. a provider of bibliographic material or information) and/or
intermediary (i.e. an agent that acts on behalf of a requester to find suitable responders).
Various interworking topologies are supported, ranging from simple two-party interactions, to multi-party interactions.

Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member
bodies). The work of preparing International Standards is normally carried out through IS0 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. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical
standardization.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication
as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
International Standard IS0 10 16 1- 1 was prepared by Technical Committee ISO/TC 46, Information and Documentation,
Subcommittee SC 4, Computer applications in information and documentation.
This second edition cancels and replaces the first edition (IS0 10 16 l-l : 1993), which has been technically revised. It includes
amendments specified in IS0 10161, DAM 1 and the corrections specified in Defect Reports l-23.
IS0 10 16 1 consists of the following parts, under the general title Information and documentation - open Systems
Interconnection - Interlibrary Loan Application Protocol Specification:
Part I: Protocol specification
Part 2: Protocol implementation conformance statement (PICS) proforma
Annexes A to D form an integral part of this part of IS0 1016 1. Annexes E to H are for information only.

Introduction
This part of IS0 10 16 1 is one of a set of International Standards produced to facilitate the interconnection of computer systems.
It is related to other International Standards in the set as defined by the Reference Model for Open Systems Interconnection
(IS0 7498). The Reference Model subdivides the area of standardization for interconnection into a series of layers of
specification, each of manageable size.
The aim of Open Systems Interconnection is to allow, with a minimum of technical agreement outside the interconnection
standards, the interconnection of computer systems:
a. from different manufacturers,
b. under different managements,
c. of different levels of complexity,
d. of different ages.
This part of IS0 10 16 1 provides a protocol specification for Interlibrary Loan (ILL) communication. The ILL protocol operates
in the Application Layer and allows the parties involved in an ILL-transaction to progress through the ILL-transaction in an
orderly and defined way.
The ILL protocol has been designed to support the ILL services defined in IS0 10 160, the ILL Application Service Definition,
which generally requires invocation of external delivery services to fulfill an ILL request. The ILL protocol carries information
that permits both automatic and operator-mediated invocation of external delivery services.
This part of IS0 10 16 1 is one of a number of related standards supporting the interconnection of library systems. These
standards can be used by themselves or in a cooperative manner to support library applications requiring a mixture of
communications services. For example, IS0 23950, which supports remote access to bibliographic databases, could be used in
conjunction with the ILL protocol to obtain item identification information. The control and management of interactions among
such bibliographic applications are local matters that are outside the scope of this International Standard.
Security and accounting issues as they relate to ILL operations are for further study.
The specification technique used in this part of IS0 1016 1 is consistent with techniques used in defining other OS1 protocols.
Within most of this document, the technique is self-explanatory. The Abstract Syntax of the ILL Application Protocol Data
Units (APDUs) is defined by means of the ASN.l specification technique specified in ISO/IEC 8824.
This part of IS0 1016 1 contains eight annexes. Annexes A to D are normative. Annex A specifies the the state tables for the
ILL protocol. Annex B specifies the encoding rules for generating a transfer syntax compatible with EDIFACT as defined in
IS0 9735. Annex C specifies the object identifiers assigned in this part of IS0 10 16 1 and registration requirements. Annex D
defines the registration procedures for ILL EXTERNAL data type definitions. Annex E is an example of an ILL EXTERNAL
data type registry entry. Annex F describes the possible mappings of this protocol onto supporting services. Annex G describes
possible methods of using a document delivery protocol in conjunction with the ILL protocol. Annex H is a bibliography.

- Part 1: Protocol specification
Protocol Specification
1 Scope
This part of IS0 10 16 1 defines the protocol for an ILL application-service-element (ASE). It specifies the behaviour which
must be exhibited by a system in order to take part in the provision of the IS0 interlibrary loan service.
It provides a formal statement of the rules of behaviour of each of the two or more entities participating in an ILL transaction. It
specifies:
a. the actions to be taken on receiving request service primitives issued by an ILL service-user;
b. the actions to be taken on receiving application-protocol-data-units (APDUs);
c. the actions to be taken as a result of events within the local system.
It provides a specification (in clause 9) of the abstract syntax required to convey the ILL protocol APDUs.
It states the conformance requirements to be met by implementors of this protocol (in clause 10).
The scope of the ILL protocol is restricted to the interconnection of systems; it does not specify or restrict the possible
implementation of interfaces within a computer system. Computer systems may range from stand-alone workstations to
mainframes.
This part of IS0 10 16 1 is intended for use by libraries, information utilities such as union catalogue centres, and any other
system which processes bibliographic information. These systems may participate in an interlibrary loan transaction in the role
of requester (i.e. an initiator of ILL requests), responder (i.e. a provider of bibliographic material or information) and/or
intermediary (i.e. an agent that acts on behalf of a requester to find suitable responders).
Various interworking topologies are supported, ranging from simple two-party interactions, to multi-party interactions.
