ISO ILL
ISO ILL
The InterLibrary Loan Protocol (ISO ILL 10160/10161) was developed to provide uniform procedures for handling peer-to-peer interlibrary loan operation between two ILL systems. The standard defines a number of messages that can be sent between the requesting site and the supplying site in order for the requester to have access to different services and material that might be offered by the supplying organization.
When a request is sent to a library this starts a new transaction. The transaction continues until the item is satisfactorily supplied and, if a loan item, satisfactorily returned, or the supplying library notifies that it cannot supply the item. Transactions may last for a few seconds or minutes, if the supplying library has electronic access to its catalogues and is supplying documents held electronically over the network, or may last for months, for example where a loaned item is renewed.
In general a transaction goes through several stages: request; failure or notification of shipping of the item; acknowledgement of receipt of the item; reminders to return loaned items; return of item or notification of lost item; acknowledgement of receipt of returned item. The standard formally divides these stages into two phases, namely the processing phase which lasts from request until either shipped notification or notification of failure to supply, followed, for loan items only, by the tracking phase.
The following diagram illustrates the workflow:

Events Table
| Triggering Event | Initiator | Service | Behavior in the receiving application |
|---|---|---|---|
| Patron requests material that does not exist locally | Borrower | ILL Request | Request is created. Lender checks if material is available. |

Security and Privacy
User authentication and authorization is out of scope of this profile. It is assumed that the ILL and Alma applications whose interactions are described in this profile trust each other.
Required Configuration in Alma
An ILL partner of ‘ISO ILL’ type should be defined, representing the institution with which a communication should be enabled. Refer to Alma online help for more information.
Required Configuration in the ILL system integrating with Alma
- The ISO messages should include the relevant fields and information, as described above.
- The URL for which ISO messages should be sent to Alma is [Alma domain]/view/iso-ill.
