Tana Hoban's fifth album in the last four years has less of the dear-cut immediacy which usually identifies her work: there are fewer close-ups and still lifes, and most of the concepts are acted out by children at play. Groups of two or three contrasting words (beside, below. . . around, across, between. . .) preface a series of photos, and this time it's left up to the child to match labels and pictures. It's a small variation on a good idea, but whether it's worthwhile to Look Again and again is another question.
