"Poor man's copyright"
Because of the cost associated with copyright registration some creators, particularly musicians, have attempted to establish evidence of ownership and creation of a work by mailing it to themselves. In the US this non-statutory practice became known as "poor man's copyright."[15] Today the US Copyright Office makes it clear that the technique is no substitute for actual copyright registration,[16] although the practice may be accepted as proof of creation in a number of national jurisdictions, such as the UK and the Netherlands. "Poor man's copyright" may also include depositing a copy of the work with a bank or attorney.[17][18]
