In preparing the affidavit, which is necessary for books only, the applicant should be careful to note the following points, as to which errors are commonly made. The affidavit should correspond exactly with the application (as that with the title-page or other data in the work itself). The affidavit cannot be made till _after_ publication and must state the exact day of publication or the date of completion, either or both, which last means not necessarily the completion of printing the whole edition, but of the deposit copies. The affidavit must be taken and signed by an individual, not by a corporation, company or firm as such, and the affiant must state whether he is the claimant, agent of the claimant, or printer, striking out the other designations. The name of the printer and binder must be given in the affidavit with city and state (but not street) address; but this means the printing and binding establishment and not the individual type-setter or binder. If the book is not bound but only issued in paper, the word "unbound" should be written into the affidavit. It is necessary to give the _venue_, that is, the county and state in which the affidavit is made, and to take the oath before a notary or other official authorized to take such oath in that locality (not merely a justice of the peace). The affiant's and notary's names should be signed exactly as written into the body of the affidavit, and the seal should correspond exactly with the name of the official and the _venue_. The signature of the affiant and of the notary and the seal are all necessary to validate the affidavit. The names and other writing should be written plainly, and the affiant should make sure to read the affidavit and compare it with the application and with the book. {Sidenote: Forfeiture by false affidavit} In case of false affidavit, forfeiture of copyright is provided (sec. 17) as follows: "That any person who, for the purpose of obtaining registration of a claim to copyright, shall knowingly make a false affidavit as to his having complied with the above conditions shall be deemed guilty of a misdemeanor, and upon conviction thereof shall be punished by a fine of not more than one thousand dollars, and all of his rights and privileges under said copyright shall thereafter be forfeited." {Sidenote: Exact compliance necessary}
