I thought Webster's was an American dictonary -
Webster's Dictionary is the title given for the common type of English language dictionaries in the United States. It is derived from American lexicographer Noah Webster and in the United States, the phrase Webster's has become a genericized trademark for dictionaries. Although Merriam-Webster dictionaries are descended from those of the original purchasers of Noah Webster's work, many other dictionaries bear his name, such as those published by Random House and John Wiley & Sons.
