Could anyone offer advice on where I might obtain copies of these two
books: (1) S.E.McGregor's book "Insect Pollination of Cultivated Crop
Plants," Agriculture Handbook No. 496 USDA, 1976, published by the
Government Printing Office, but now out of print; and (2) "American Honey
Plants" by F.C. Pellett? I'd also appreciate any suggestions on
wildflowers as nectar and pollen sources. Thanks.
