You may return books from any of the three Durham libraries (Main library, Palace Green and Education) to the Queen's Campus library, unless the item is from the Short Loan collection. Short loan material must be returned to the issuing library. You may also return a Queen's Campus library book to any Durham library.
However, aside from Stockton returns, books from the Durham-based libraries must be returned to their home library. For example, you cannot return a Main library book to the Education library.
