My first response was "No censorship" then I considered that we have some things which are considered to be unacceptable. A book which denied the Holocaust, for example. Speech doing such a thing is strictly regulated, so perhaps books should be as well. I'd prefer not to see any but I'm afraid it may sometimes be necessary. I'm still wavering however.
If you read the library's link you will see that it was emphasised that one of their criteria is/was the law.
"Calderdale Libraries and Information follows the guidelines laid down by the Chartered Institute of Library and Information Professionals (CILIP 2005):
Access should not be restricted on any grounds except that of the law. If publicly available material has not incurred legal penalties, then it should not be excluded on moral, political, religious, racial or gender grounds, to satisfy the demands of sectional interest. The legal basis of any restriction on access should always be stated.
We aim to provide, within budgetary limitations, a wide range of stock that promotes all aspects of life and reflects all shades of opinion. Each item will be evaluated and judged by the standards and selection criteria set out in this policy.
