17 USC 407 - Deposit of copies or phonorecords for Library of Congress

(a) Except as provided by subsection (c), and subject to the provisions of subsection (e), the owner of copyright or of the exclusive right of publication in a work published in the United States shall deposit, within three months after the date of such publication
(1) two complete copies of the best edition; or
(2) if the work is a sound recording, two complete phonorecords of the best edition, together with any printed or other visually perceptible material published with such phonorecords.

Neither the deposit requirements of this subsection nor the acquisition provisions of subsection (e) are conditions of copyright protection.

(b) The required copies or phonorecords shall be deposited in the Copyright Office for the use or disposition of the Library of Congress. The Register of Copyrights shall, when requested by the depositor and upon payment of the fee prescribed by section 708, issue a receipt for the deposit.
(c) The Register of Copyrights may by regulation exempt any categories of material from the deposit requirements of this section, or require deposit of only one copy or phonorecord with respect to any categories. Such regulations shall provide either for complete exemption from the deposit requirements of this section, or for alternative forms of deposit aimed at providing a satisfactory archival record of a work without imposing practical or financial hardships on the depositor, where the individual author is the owner of copyright in a pictorial, graphic, or sculptural work and
(i)  less than five copies of the work have been published, or
(ii)  the work has been published in a limited edition consisting of numbered copies, the monetary value of which would make the mandatory deposit of two copies of the best edition of the work burdensome, unfair, or unreasonable.
(d) At any time after publication of a work as provided by subsection (a), the Register of Copyrights may make written demand for the required deposit on any of the persons obligated to make the deposit under subsection (a). Unless deposit is made within three months after the demand is received, the person or persons on whom the demand was made are liable
(1) to a fine of not more than $250 for each work; and
(2) to pay into a specially designated fund in the Library of Congress the total retail price of the copies or phonorecords demanded, or, if no retail price has been fixed, the reasonable cost to the Library of Congress of acquiring them; and
(3) to pay a fine of $2,500, in addition to any fine or liability imposed under clauses (1) and (2), if such person willfully or repeatedly fails or refuses to comply with such a demand.
(e) With respect to transmission programs that have been fixed and transmitted to the public in the United States but have not been published, the Register of Copyrights shall, after consulting with the Librarian of Congress and other interested organizations and officials, establish regulations governing the acquisition, through deposit or otherwise, of copies or phonorecords of such programs for the collections of the Library of Congress.
(1) The Librarian of Congress shall be permitted, under the standards and conditions set forth in such regulations, to make a fixation of a transmission program directly from a transmission to the public, and to reproduce one copy or phonorecord from such fixation for archival purposes.
(2) Such regulations shall also provide standards and procedures by which the Register of Copyrights may make written demand, upon the owner of the right of transmission in the United States, for the deposit of a copy or phonorecord of a specific transmission program. Such deposit may, at the option of the owner of the right of transmission in the United States, be accomplished by gift, by loan for purposes of reproduction, or by sale at a price not to exceed the cost of reproducing and supplying the copy or phonorecord. The regulations established under this clause shall provide reasonable periods of not less than three months for compliance with a demand, and shall allow for extensions of such periods and adjustments in the scope of the demand or the methods for fulfilling it, as reasonably warranted by the circumstances. Willful failure or refusal to comply with the conditions prescribed by such regulations shall subject the owner of the right of transmission in the United States to liability for an amount, not to exceed the cost of reproducing and supplying the copy or phonorecord in question, to be paid into a specially designated fund in the Library of Congress.
(3) Nothing in this subsection shall be construed to require the making or retention, for purposes of deposit, of any copy or phonorecord of an unpublished transmission program, the transmission of which occurs before the receipt of a specific written demand as provided by clause (2).
(4) No activity undertaken in compliance with regulations prescribed under clauses (1) or (2) of this subsection shall result in liability if intended solely to assist in the acquisition of copies or phonorecords under this subsection.
