Quotation - "Many of Bailey's methods would later become important dictionary-making conventions. For example, Bailey explored the origins of words, for which he drew on his knowledge of Hebrew, Greek and Latin; he provided advice on pronunciation; and he attempted to compile a more complete list of words than any other English dictionary writer before him, squeezing in not only specialist or 'hard' words, but also dialect, slang and taboo words. The fact that he included rude or slang words shows that his work was far ahead of its time - such words were left out of most non-slang dictionaries until well into the 19th century."
