Structure:

The copyright article-fee code is composed of five parts:

1) the International Standard Serial Number (ISSN) or the International Standard Book Number (ISBN), an eight- or ten-digit number constructed according to ISO 3297 or 2108;

2) the last two digits of the year of publication of the component part;

3) the item number, an eight-digit number designed to guarantee the uniqueness of the code;

4) a per-copy fee, a four-digit number giving the fee for photocopying the work, stated in local currency (e.g., U.S. or Canadian dollars); and,

5) the author-royalty indicator, a one-digit number indicating that there is a royalty agreement with the author(s) (1) or there is no royalty agreement (0).

The code contains slash marks ( / ) between each part except between the item number and the per-copy fee, where a currency mark (e.g., the dollar sign "$") is used. For fees given in U.S. and Canadian dollars, the per-copy fee contains a decimal point after the second digit.
