Part One of this article, a review of the main series available in Japan, is based on data collected by EPER (Edinburgh Project on Extensive Reading) over 20 years. The data is available through a unique library of graded readers to which publishers have contributed copies of their titles since 1981. All titles have been read and assessed for level of difficulty and quality, and the initial verdicts have been modified where necessary in the light of feedback from students. Part Two, Selection of Titles, discusses the criteria to be used in selecting titles and is based on EPER's experience of advising on the design, implementation and evaluation of reading programmes, a number of which over the last three years have been in Japanese universities and junior colleges. An important element of our advice is the provision of lists of recommended titles.
