Schools in America are to drop classic books such as Harper Lee's To Kill a Mockingbird and JD Salinger's Catcher in the Rye from their curriculum in favour of 'informational texts'.

American literature classics are to be replaced by insulation manuals and plant inventories in US classrooms by 2014.

A new school curriculum which will affect 46 out of 50 states will make it compulsory for at least 70 per cent of books studied to be non-fiction, in an effort to ready pupils for the workplace.

Books such as JD Salinger's Catcher in the Rye and Harper Lee's To Kill a Mockingbird will be replaced by "informational texts" approved by the Common Core State Standards.
