New bulletins often use other bulletins’ articles, in which case they need to obtain permission. (See also Chapter 7 on using existing materials). Make sure that you are asking permission from the person or organization that has the copyright. In most cases bulletins will find that other publishers are generous in granting permission for articles to be copied provided that the source is mentioned. Copyright also applies to tables, graphs and illustrations, such as photographs and cartoons. If a bulletin wants to copy an illustration, they will need to get permission from the copyright holder.
