After receiving peer commentary and suggestions for improvement, “he made changes and added to its contents, culminating in the second edition published in 1228” (Devlin, Finding 85-86). “When he finished writing it, he would have taken it to a local monastery to have copies made by the monks.” This is such a laborious method of publication that it could have taken a year or more to copy a manuscript as long as Liber Abaci (over 400 pages).

Thus, in the preface of the second edition he revealed something of the intellectual heritage which inspired him to write the book in the first place. But Leonardo seemed very occupied with producing practical solutions to common problems. The first edition of Liber Abaci was a dense work suited more to scholars than the average man. He says, “Mathematical truth is completely independent of human judgment, immutable, eternal, forms its own abstract world,” so, “to the mathematician, the historical details are of little relevance it doesn’t matter when someone first proved a theorem the focus is on the development of the ideas and how one train of thought led to another” ( Finding 69). Mathematician/ historian Devlin explains this is because “most mathematicians are interested in mathematical results, not the people who discover them” ( Finding 68). It was uncommon for mathematically-focused texts to include such information. No one knows why Leonardo dedicated the book to Michael Scotus, who was the court astrologer to Holy Roman Emperor Frederick II, nor why he included the autobiographical information (Devlin, Man 43). This book provides almost the only biographical information we have about him.
