This has been a great discussion but one topic that no one has mentioned is if
 this type of shelving actually hinders access to the periodicals collection
 for the physically challenged. I'm not sure if it's any worse than open
 shelving but I would imagine (especially for the wheel-bound) that hinged
 shelving might be even more difficult to use. Has anybody done any research,
 have experience in this etc?
