Postal loans

Items can be sent by post anywhere in the UK. We use Royal Mail and Fellows and Corporate Patron companies can choose to have items posted by First Class or Special Delivery (there are some items which must be sent Special Delivery). We ask that you return the cost of postage, for which an invoice will be enclosed.

We are now able to post items to most countries in Europe using Special Delivery. This is at the Librarian’s discretion and dependent on postal guarantees/insurance.

The loan period is 4 weeks. Loans can be renewed for an unlimited number of 4 week periods provided they are not required by another reader.
