if the parties expressly agree in a written instrument signed by them
that the work shall be considered a work made for hire....

The authors of a joint work are co-owners of the copyright in the work,
unless there is an agreement to the contrary.

Copyright in each separate contribution to a periodical or other
collective work is distinct from copyright in the collective work as a
whole and vests initially with the author of the contribution.


Two General Principles

+ Mere ownership of a book, manuscript, painting, or any other copy or
phonorecord does not give the possessor the copyright. The law
provides that transfer of ownership of any material object that
embodies a protected work does not of itself convey any rights in
the copyright.

+ Minors may claim copyright, but state laws may regulate the business
dealings involving copyrights owned by minors. For information on
relevant state laws, consult an attorney.
