Boston Public Library is importing their item barcode from their Polaris catalog into Aeon via Z39.50. They would like to be able to map the barcode value to the Aeon Item Number field, which is not currently possible. There is also an ILLiad UserVoice asking for this feature: https://uservoice.atlas-sys.com/forums/581665-illiad-ideas/suggestions/39458122-add-additional-result-mapping-options-for-z39-50
