There are two main differences between this special series and t h e regular Book Review feature which appears a t t h e back of each issue of t h e JOURNAL. De Libris Judicia will urovide a critique by secondary teachers of books which were originally designed for college use or for a discipline other than chemistry a n d which might be worthwhile t o the secondary teacher. You will also notice the unique pairing of reviews which will be apparent as a part of De Libris Judicia. Two independently written critiques of the particular book will be run in tandem. Because of page limitations, t h e reviews will, from time t o time, be condensed. T h e candid expressions of opinion by the individual reviewers will, however, not be sacrificed. W e wish t o thank all of you who have taken the time t o read t h e books, analyze them, a n d write t h e reviews.
