Copyright and Liscences

by Matty Wacht

What is a copyright?

A copyright is the collection of rights granted to the author of a piece of work (book, song, video, software, et cetera). Some of these rights are the right to sell, alter, lease, or lend the work.

Public Domain

When a copyright expires (i.e. upon the author's death), the product is given to the public domain license and is no longer protected by copyright. Examples of this include classic literature and music.
