July and August are prime time for preserving garden-fresh produce. Marion City Library recommends several how-to books on canning, freezing, and new recipes: “Preserve It,” by Dorling Kindersley; “Preserving the Fruits of the Earth,” by Stanley Schuler; “The Complete Freezer Cookbook,” by Madeline Fraser; “Canning and Preserving,” by Sunset; “Preserving,” by The Good Cook; and “The Complete Book of Home Preserving,” by Ann Seranne.
