(11) for any other special services requiring a substantial amount of time or expense, such fees as the Register of Copyrights may fix on the basis of the cost of providing the service. (b) The fees prescribed by or under this section are applicable to the United States Government and any of its agencies, employees, or officers, but the Register of Copyrights has discretion to waive the requirement of this subsection in occasional or isolated cases involving relatively small amounts. (c) All fees received under this section shall be deposited by the Register of Copyrights in the Treasury of the United States and shall be credited to the appropriation for necessary expenses of the Copyright Office. The Register may, in accordance with regulations that he or she shall prescribe, refund any sum paid by mistake or in excess of the fee required by this section. Section 709. Delay in delivery caused by disruption of postal or other services. In any case in which the Register of Copyrights determines, on the basis of such evidence as the Register may by regulation require, that a deposit, application, fee, or any other material to be delivered to the Copyright Office by a particular date, would have been received in the Copyright Office in due time except for a general disruption or suspension of postal or other transportation or communications services, the actual receipt of such material in the Copyright Office within one month after the date on which the Register determines that the disruption or suspension of such services has terminated, shall be considered timely. Section 710. Reproduction for use of the blind and physically handicapped: Voluntary licensing forms and procedures. The Register of Copyrights shall, after consultation with the Chief of the Division for the Blind and Physically Handicapped and other appropriate officials of the Library of Congress, establish by regulation standardized forms and procedures by which, at the time applications covering certain specified categories of nondramatic literary works are submitted for registration under section 408 of this title, the copyright owner may voluntarily grant to the Library of Congress a license to reproduce the copyrighted work by means of Braille or similar tactile symbols, or by fixation of a reading of the work in a phonorecord, or both, and to distribute the resulting copies or phonorecords solely for the use of the blind and physically handicapped and under limited conditions to be specified in the standardized forms.
