Title: The First Line (magazine)
Content:  The purpose of The First Line is to jump-start the imagination—to help writers break through the block that is the blank page. Each issue contains the best short stories stemming from a common first line, with no restrictions on genre, style, or school of thought. It's an exercise in creativity for writers, and a chance for readers to see how many different directions writers can go in when they start from the same place. The First Line also provides a forum for discussing favorite lines in literature through academic or personal essays. Most of the first lines are created by the editors. Every two or three years TFL holds a contest where readers submit possible first lines, and a few are chosen for publication. Although the majority of authors are from the United States, TFL has published authors from India, South Africa, Egypt, Denmark, Estonia, and Australia, as well as Canada and the UK, just to name a few.
