Retrieving materials can be time-consuming
Even if all of your material is on-site, it may be stored in several different places. For example, photographs might be in cold storage, while maps are in flat storage, books in one range of shelving upstairs, and boxes in another range of shelving downstairs.
Therefore, it could take a while for us to locate all the pieces that can help you in your project. If you contact us ahead of time, we can gather all of your materials and put them on hold for you, so they are ready when you arrive.
