I don't know what the arrangements are for access for the books moved off site, but in my experience, when done right it is very convenient for researchers. My former university moved all the older science books and journals off publicly accessible shelves. Now you put in an online request for the article or chapter you want and within 24 hours you get a scanned pdf. Since this is exactly what I would be doing myself anyway, the system made it much more convenient to access chapters of books that are not available digitally online. As a researcher, I care about the information, not the library building. Not having to go to the library is a convenience.
