This library has a large DVD section, and if I could stand up long enough to go through each set of shelves, I could probably find a lot of good British dramas. But they don’t separate the British drama from American movies, so I’ll have to plan on standing for 15-20 minutes. Difficult.
Do they have an online reserve system? In both my county systems, they will pull items to the reserve shelf, even if they were sitting in the stacks in the same library.
talk to your librarian. Have them print out a catalog and if you can get them to isolate British, all the better. Then you can have them pull them for you and have them at the desk.
It should all be computerized.
Also in many states there is interlibrary loan, and you can have them find what you want in all the other libraries in the state.
