15. Other residents, and non-resident employees in the borough, over twelve (fourteen) years of age, may borrow books, but must first obtain a guarantee (or recommendation) from a duly qualified person, as defined in Rule 14, and must sign an application for a borrower’s ticket, on forms to be provided by the librarian. But no such guarantor shall be allowed to assume responsibility for more than three other persons, unless by special arrangement with the committee, and in no single case shall his or her liability exceed £2 per person guaranteed. 16. Any person resident or employed in the borough, unable to obtain the signature of a qualified resident as a guarantee, may borrow books on leaving a deposit of 10s. with the librarian. The guarantee of the recognized head officials of Government departments, Friendly Societies and similar organizations may be accepted at the discretion of the Committee in lieu of an ordinary guarantee, for persons who are employed in the district. 17. The Application and Guarantee Form, duly signed, must be delivered to the librarian, and if, on examination, it is found correct, the borrower’s ticket will be issued three days (_or_ at once) after (excluding Sundays), but will only be delivered to the borrower in person. This ticket will be available at the central library or any branch or branches. 18. In accordance with Section 11 of the Public Libraries Act, 1892, the committee will lend books to persons, other than those duly qualified under Rules 13-16, who pay an annual subscription of 7s. 6d.; but such borrowers must conform, in every respect, to all the rules of the library, and shall have no privileges other than those possessed by the other borrowers. 19. The committee shall issue additional tickets to readers, available for all classes of literature save Fiction. Any duly enrolled borrower may have one of these extra tickets on filling up an application form as for an ordinary ticket. School teachers may have more than one ticket of this class on application to the librarian. 20. All tickets and vouchers must be renewed annually, each ticket and voucher being reckoned available for one year from date of issue.[13] [13] In some libraries the practice has arisen of making tickets permanent, as long as the holder resides in the district, without renewal annually. In place of renewal, a revision takes place, to ensure accuracy of addresses, etc.; where this is so, Rule 20 is unnecessary.
