Payment First-time advertisers or agencies are required to pay at the time of the initial order. Other accounts are payable within 30 days of the invoice. Non-U.S. advertisers are required to pay in U.S. currency at the time of the initial order. Advertisers and their agencies have dual liability for payment. Conflicting agreements between advertisers and agencies, even if listed on insertion orders, are superseded by this condition of the American Library Association.
All advertising is subject to publisher's approval.
Cancellations are not accepted after the closing dates for space reservations. Covers and special positions cannot be canceled. All cancellations must be confirmed in writing.
