Jacob Abbott 
History of King Charles the First of England 

The history of the life of every individual who has, for any reason, attracted extensively the attention of mankind, has been written in a great variety of ways by a multitude of authors, and persons sometimes wonder why we should have so many different accounts of the same thing. The reason is, that each one of these accounts is intended for a different set of readers, who read with ideas and purposes widely dissimilar from each other. Among the twenty millions of people in the United States, there are perhaps two millions, between the ages of fifteen and twenty-five, who wish to become acquainted, in general, with the leading events in the history of the Old World, and of ancient times, but who, coming upon the stage in this land and at this period, have ideas and conceptions so widely different from those of other nations and of other times, that a mere republication of existing accounts is not what they require.
