Introduction to Copyright
Copyright, unlike patent, is not something you have to apply for—it vests the minute you fix something creative in a tangible form and, in general, it lasts for the life of the author plus 70 years (there are some exceptions). In other words, nearly all authors are technically copyright holders. Put another way, just because something is published does not it mean it isn't copyrighted. It's true that some authors don't elect to register their copyrights or enforce them but they have the right to do so for their entire lives, and their heirs can enforce the rights for 70 years beyond that.
An author does not need to register his/her copyright in order to have rights—the author just needs to register before bringing a lawsuit for infringement. In other words, just because something isn't labeled "© date" doesn't mean it isn't copyrighted, and failure to register the copyright does not mean the author has abandoned his/her rights.
Just because something is published does not mean it's in the public domain. Something is only in the public domain when the intellectual property rights have expired (for example, the copyright term has expired after 70 years plus the life of the author), or the intellectual property rights have been forfeited (for example, by a non-enforcement covenant or judicial ruling).
