What is the Public Domain?
Works which are not protected by any intellectual property laws such as copyright are considered in the public domain. Usually works enter the public domain because:
These are free of any type of restrictions and can be reused in any form without permission. Although individual public domain works do not have any restrictions on use, collections of public domain works can. For example, if someone publishes a collection of essays which are all in the public domain the collection itself would have a copyright but each individual essay would still be in the public domain.
What's in the Public Domain?
Generally each year on January 1st a new group of works have their copyright expire and enter the public domain. This day is know as Public Domain Day and the list of new works is released. There currently is not a complete list of public domain works online, but there are many resources available to find content.
These resources contain works which are believed to be in the public domain. It's important to review each source before use.
