A few years ago Mr. Carlsen appeared as a fresh wind from the west to talk specifics about teen-age book selection, and his book comes complete with endorsements from ALA, the International Reading Association and the National Council of Teachers of English--so you had better buy it. You can also throw out your old copies of Top of the News containing his two ALA talks, for most of the material is included here,--along with advice to parents on letting youngsters proceed at their natural pace (even if they. pause at such sub-literature as comics and series books); and how to handle the hard-core problem of pornography. The remaining sections feature various categories of adult books, from the Classics to the Wonderful World of Non-Fiction, with examples described in detail and annotated lists appended. A certain creeping dullness sets in during these sections, but only reviewers will have to read it whole; the approach is wholesome, the advice is Sensible, the range is enormous--and parents will profit.
