It is not necessary to display the codes specified in this document to library users and staff.
Codes and encoded information may be mapped to alternate values or be presented in the language of
the ILL application's user interface. For example, if Library XYZ (using English) sends a request to Library ABC (using Danish),
then codes and encoded information is presented in English in the ILL application of the requesting
library and in Danish in the ILL application of the supplying library. 2. Use of AnswerYesNo in the Supplying Agency message
In the Supplying Agency message -> MessageInfo inclusion of the element, AnswerYesNo is limited to

to another address. 7. Multi-volume requesting
7.1 Sending a request for a multi-volume title
When the requesting library is sending a request for a specific volume or volumes, or all
volumes from a multi-volume title then the volumes should be indicated using the Volume element (repeatable), in the
BibliographicInfo section of the Request message.
See Use Case 21 &
Use Case 21a for examples.
7.2 Responding to a request for a multi-volume title
There are three ways in which a supplying library may respond to a request for a multi-volume title
7.2.1 If there is no indication in the Request message
that a specific volume or volumes are needed
If during the process of filling a request, staff at the supplying library determine that there are multiple
volumes associated with the title requested, but the requesting library has not specified which volume are volumes
are needed, then the supplying library should send a Status of RetryPossible in the SupplyingAgency message and
indicate which volume or volumes are available.
See Use Case 22a for an example.
The requesting library can then
submit a RetryRequest indicating which volume or volumes are needed. See Guideline 8.
7.2.2 If the request specifies which volume or volumes to
supply and the supplying library CAN provide ALL the volumes requested
If the request includes which volume or volumes are needed, then the supplying library can send multiple
ItemId elements (one for each volume supplied) in the DeliveryInfo section of the SupplyingAgency message. The
supplying library may also include the volume numbers supplied in the Note element of the MessageInfo section. If
volume numbers are provided, they should be listed in the same order as the list of ItemIds.
See Use Case 21 for an example.
7.2.3 If a specific volume or volumes are indicated in
the request and the supplying library CANNOT provide ALL the volumes requested
If the request includes which volume or volumes are needed, but the supplying library cannot provide all
the volumes requested, then the supplying library should send a Status of RetryPossible in the SupplyingAgency message
and indicate which volume or volumes are available.
See Use Case 21a for an example.
The requesting library can then
submit a RetryRequest indicating which volume or volumes to supply. See Guideline 8.
8. Sending a Retry request for a multi-volume title
After receiving a Status of RetryPossible from the supplying library, indicating which volume or volumes
of a multi-volume title are available, the requesting library can send a Retry request. The specific volume
or volumes should be indicated using the Volume element (repeatable), in the BibliographicInfo section of the
Request message.
See Use Case 21b and
Use Case 22b for examples.
9. Sending a Patron request
When a patron is using an OPAC or search portal which includes an option to submit
a request, then the OPAC or search portal can use the Patron request to submit the request
to the patron's local interlibrary loan system for further processing and fulfillment. 10. Sending a Transfer request
When a library uses more than one ILL system,then the Transfer request can be used to
transfer requests between systems. The library may send the request id from the initiating
system as part of the Request message. 11. Requesting and sending an item using Odyssey delivery
When the requesting library is requesting delivery of a document via Odyssey, the
ElectronicAddressType = Odyssey should be used. Note: a new Open Code value of Odyssey has been
registered for ElectronicAddressType. 12. Indicating the version of ISO18626 in use
Currently there are 3 versions of ISO18626 in use. When two ILL systems are interoperating using
two different versions of ISO18626, e.g., ISO18626:2017 and ISO18626:2021, then the version number in use
should be provided in the XML header of each message using the format provided in the following table. |
