This answer above would be highly unlikely. Libraries are strongholds of support for constitutional freedoms.
Members of the public who want to dictate who-can-read-what according to their own particular views often request that libraries remove books they disapprove of. This is rarely, if ever, done because libraries provide a broad range of types of information for everyone.
Even if access to a book is limited, books are not banned by libraries.
However, libraries can not buy and store every book published. Librarians choose books through selection processes that provide for a good general coverage of areas of knowledge and deeper coverage of areas of interest to their users. So, one library might have very little on marine biology but have lots of cookbooks. Another library might have very little on automobile repair but have lots of books on music. Although some areas might have lesser coverage in a particular library's collection, books are not banned in these areas.
Individual members of the public who want to personally dictate what information others have access to try to ban books.
Associations/organizations that want to dictate what information others have access to try to ban books.
Librarians and libraries do not ban books.
