The answer is "True".
After 9 years of work, Johnson finished "The Dictionary of the English Language" in 1755. He would later start working on other literary projects such as "The Idler" in 1758, which was series published in a weekly news journal called The Universal Chronicle. Since it did not occupy all of his time he decided to write a novel called Rasselas, which was finished on 19 April 1759.
