A collection is a group of chapters put together from the same book, different books, new chapters created, and a combination of any of those 3. This new grouping of chapters is called a “Collection” which can be for personal use or published for a price. Chapters taken from others must have the author's permission for further selling of chapters used. Work published by another user with your chapter(s) included will provide you with another selling angle. Only you will get royalties from your chapter(s), even in new collections created by other users.

As an author, you can allow your chapters to be sold and used individually to form Collections. You can select which chapters others can use to create collection materials for further selling. This will give your work another selling angle. Only you will get royalties from your chapters, even in new collections created by other users. 

As a reader, you can group together chapters from various books where authors have permitted this use and create customized collections of chapters for personal use or for profit. Royalties will be calculated from the remaining amount after subtracting the cost of used materials that aren’t your original work. For example, you charge $5 for your published work but used a chapter from another author that costs $1. Royalties will be applied after subtracting the cost of materials used ($1) from your newly published work ($5). This means the royalties from the $1 chapter will go to the original author and the $4 left will be where your royalties get computed from.
