A group of school librarians are planning to lobby parliament for school libraries to be made statutory. This protest is planned for 29th October, 2012, which is during school half term. You can finds more information here.
This is not a demonstration but a lobby, so please contact your MP in order to lobby them on the day, or you can along on the day and show your solidarity.
A similar event was held on 13th March 2012 by Speak Up for Libraries, of which The Library Campaign is a part, in support of public libraries, and was very successful.
The thought behind the School Libraries Lobby is that if school libraries were on the Ofsted Inspection Schedule then that would force schools to keep libraries open and to think seriously about their provision.
