LEGAL EAGLES: TAKE CARE TO STAY WITHIN THE BOUNDS OF THE LAW
British copyright law is one of the tightest in the world, designed to prevent any copying of original work.
"You are not allowed to make a substantial copy of any copyright work, either as a whole or any component part," explains Anna Booy, a solicitor specialising in intellectual property law. There are very few exceptions to this.
Teachers and students are allowed to cite quotes out of copyright works for study purposes, and critics may reprint short sections in reviews.
