Although some manuals may not be available through interlibrary loan, the information may be obtained in another form.
Some manuals are only available from the manufacturer.
The manufacturer's name, address, and telephone number will be given to the patron if necessary. Door latch, transmission, fuel injection, vacuum system, etc. Indicate if the patron knows whether information from previous years will suffice. For example, some truck wiring diagrams will be identical for several different model series or identical for 2-3 years. Manuals may not circulate, but photocopies of the information needed may be easier to obtain.
