My insistence over the years on this website about the powerful, indispensable link between reading and writing finds support in Lisa Fink's brief article "The Relationship Between Writing and Reading," for the National Council of Teachers of English website and in a more extensive essay, "The Reading-Writing Connection," by the International Literacy Association (formerly International Reading Association), appearing in the Electronic Registration Infomation Center (ERIC) website.
If you overlook the emphasis of these articles on elementary and secondary school students, you will see how much their ideas and suggestions apply to business and technical writers as well.
