Keep in mind that a manuscript with outstanding permissions cannot be considered ready for publication. Once you have determined which items require permission, you should organize your material and apply for permissions as soon as possible according to the procedures outlined below. This number represents the total number of words. That is, if you use material from a source throughout your work, all of the quotations contribute to the 500-word limit.
Permission is necessary for any artwork from another source.
If the art is from a secondary source, with a printed credit to a primary source, we only need permission from the primary source. However, if the secondary source adapted the art and we want to use that design, we must have permission from both sources. Permission is necessary for even one line of a poem or a song. Permission is necessary for unpublished theses, speeches, and letters. The content of a letter belongs to the person who wrote it, not the recipient.
