2 External System and OCLC ILL ConsiderationsOverviewThe capabilities of your external system or Web interface determine which ILL Direct Request option you choose. You must thoroughly understand how your system or Web interface works to successfully implement ILL Direct Request. Information in the request can be supplied by an external system or your local system. Using Direct-to-Profile processing, information can also be supplied by OCLC constant data and custom holdings. Factors to consider about information in the request include:
System functionsThe following checklists help you determine which ILL Direct Request option you can use. They are not intended as sets of requirements. Capabilities differ from system to system. It is unlikely that any system includes all functions. Direct-to-Profile Processing Checklist
Direct-to-Lender Processing Checklist
Direct-to-Review File Processing Checklist
Mapping data to the OCLC ILL request formYour system may track more information about a patron request than is normally provided in an OCLC ILL request form. Discuss mapping data with your Systems Manager. For example, you can map additional information from your system (such as local holdings information) in the OCLC ILL field:VERIFIED:. Order in :Lender:A preference code in the ISO-10161 ILL-Request allows you to restrict the order of symbols in your lender string. Set this option to ordered if you do not want ILL Direct Request to change the order of lender symbols you supply. However, this has implications for building a :Lender: field. Example: You set preference to ordered and provide 25 potential lenders in a request. The fourth symbol in your string of 25 is not a valid OCLC lender. ILL Direct Request puts symbols 4-25 in the :LOCATIONS: field. The request is left with only 3 potential lenders. In the example, if preference is unordered, ILL Direct Request puts the invalid symbol in :LOCATIONS: and continues to validate symbols until the :Lender: field is full. Constant data considerations (Direct-to-Profile)Data from the ISO-10161 ILL-Request takes precedence over data from the constant data record (for example, if the ISO-10161 ILL-Request contains :MAXCOST:, then :MAXCOST: is not applied from constant data). You must decide which data should be supplied in the ISO-10161 ILL Request and which data should be omitted so it can be supplied by a constant data record. The following fields in an OCLC ILL request may be supplied by a constant data record if they are not furnished in the ISO-10161 ILL-Request.
Detecting duplicate requestsILL Direct Request creates a duplicate detection key for each request using the patron name, title, and article information. If ILL Direct Request finds an ILL or Review file record with the same duplicate detection key, the request is considered a potential duplicate. As seen in the following table, only Direct-to-Profile processing can be affected by the identification of a potential duplicate:
Duplicate noteIn Direct-to-Profile and Direct-to-Review processing, ILL Direct Request puts the following note in the :DIRECT NOTES: field: this request may duplicate request: [ILL request or Review File numbers]. Examples: This request may duplicate request il: 1707349. |
