Whether you’re circulating a periodic publication or writing a book, WordPress provides an easy way to organize and structure your content while it’s in process. Posts can be kept private while you’re working on finishing the book. Alternatively, you can release installments of your work to the public by publishing them on your WordPress site. This option gives you the benefit of community feedback during the process of writing your book.
Whatever process you choose to enhance your workflow is up to you. WordPress offers the flexibility and tools for any approach and provides several advantages over traditional publishing houses
