After you have decided that you should register your work, the next question is, of course, how to do so. For most works, you can register online through the Copyright Office's website. Usually, if you file online, there is a $35 fee. To file in print, the fee is $85. Registration for certain types of works, including things like masks and vessel hull designs, can only be filed in paper at this time. If you're curious about additional fees from the Copyright Office, see Circular 4 for more information.
