While in school in the 1930s, Arthur C. Clarke had already developed a keen interest in science and speculative fiction. This notebook from his school days in Taunton, Somerset, recorded his program of reading, in which he not only lists authors/titles, but his assessment of individual works (“G” for good, “VG” for very good, etc.). The notebook also is an indicator of Clarke’s systematic approach as he researched his interests—a characteristic continued through his professional life.
