These books are indispensable for identifying the plants and animals found along the North Atlantic seashore. These should be available at any major bookstore.
A good project for rainy days and snowed-in weekends is to go through the plates ( illustrations ) in your field guides and highlight all the species that are found in your area. This will make the guides far more useful, and also give you a chance to become more familiar with the plants and animals you may encounter. Beats watching television.
