In the first sentence of the Preface, the phrase "I found that there are a lot of good articles" is confusing as to who "I" is. Since there were many contributors, if there is one person in charge (who apparently is the "I"), his or her name should be made clear at the beginning or end of the Preface.

This brings me to my next point, the confusion of whether to use "he" or "she" or "he/she" for the reader.
