This is a statutorily defined document.
Copyright material is intellectual property, and is legally actionable.
Use of copyright materials is sometimes very sensitive. Intellectual property laws are very much in favor of the owners of copyright, and you're strongly advised to be extremely careful in the use of any non original materials.
It's very important to be specific about which materials you're requesting the right to use, and in what context.
Do not, ever, use any other copyright materials on the basis of an implied permission from the copyright owner, even if the permission seems to allow it.
Written permission must be obtained, prior to any use of copyright works.
Use only the materials specifically referred to in the letter of permission.
It is advisable to forward to the copyright owner a pre publication /distribution copy of materials to allow any objections to be made.
Note: When using copyright materials, accreditation to the copyright owner must be given.
Any use of materials outside terms of permission could be actionable.
As you can see from the example below, the copyright owner is fully briefed on the intended use, place of publication / distribution and the context in which their materials are used.
