Two useful sites for OSU space-related documents:

Rick Stoddart mentioned this resource: Learning Space Toolkit
These are sites that inspire thinking/planning about 5th floor space in Valley:
University of South Carolina Special Collections Building
North Carolina State visuals for Special Collections:
DH Hill Naming Opportunities (see those related to special collections)
Hunt Library Naming Opportunities (there are several links here but check out Skyline Reading Room as a starting place)
Some other inspirational spaces are within the newly renovated UCLA Charles E Young Research Library as well as the University of Calgary's Taylor Family Digital Library (a Youtube video from a CNI presentation).
