At present this collection only includes household and professional invoices and receipts from various companies in York and elsewhere, sent to Milburn in the course of his professional and personal activities. Original order has been maintained by the archivist, and bundles have been repackaged as found.
This collection has been severely damaged by rodents before transfer to the archive, leaving the invoices very fragile. They require conservation cleaning and stabilisation before they can be made available to the public.
