Additionally, many things are in the public domain, such as the game of Bingo, because no one really knows who first made up the game. However, if you get an idea for something, such as a game which is an adaptation of someone else s game you must write the publisher and ask permission to use it. When asking for permission, you should generally include a copy of your game and explain how it is similar to the publishers . Usually the publisher will grant permission while asking you for some small payment. Moreover, if you use their materials in something which earns you money, you should pay the students for it.
Different publishers have different ways in which they want to receive a book.
Prentice-Hall wants you to write a proposal and on request they will send you a copy of their proposal guidelines. Other publishers will take your entire manuscript, but usually publishers want an outline and a few sample chapters. Some publishers want to see your ideas before you finish writing the complete manuscript. All publishers will ask you to revise what you have written according to some format and so want to advise writers how to proceed. Sending a letter to a publisher briefly explaining your book and asking if they are interested in seeing a copy can also be helpful.
