b. In the case of assignments, etc., and notices of intention to use, a copy of the particular document to be recorded, even if another, non-identical copy is later substituted for purposes of recordation. In the case of notices of use, 8 copy of the notice containing the name of the copyright claimant and at least one of the titles in the notice as eventually recorded. For example, if before November Z7, 1965, the only notice of use received contained the names of different copyright claimants for several different compositions, the fee for the notices of use eventually recorded should be computed at the new rate.
C. Where, before November Z7, 1965, we find that the higher fee will be necessary unless there is a satisfactory compliance before that date, we will call attention to the fee increase in the correspondence in a manner calculated to avoid the necessity of writing later for an additional fee.
D. Where the applicant, at his own initiative, indicates that he prefers to pay the higher fee for a registration in a case that was pending in the Copyright Office at the time of the fee increase, the higher fee will not be refused even though the circumstances would not make it mandatory.
