{"product_id":"9780914025269","title":"The Nautical Almanac 1981 - For Training Purposes Only","description":"Data in this book are no longer valid for navigation. It is preserved in print because many training programs (including USCG and US Navy ) use examples from 1981 to teach celestial navigation. USCG license exams require data from this almanac. These exams also require Sight Reduction Tables, Pub 229, Vol. 2 and a 2102-D Star Finder.","brand":"starpath publications","offers":[{"title":"Default Title","offer_id":49778536120560,"sku":"9780914025269","price":39.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9780914025269_p0.jpg?v=1780090732","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780914025269","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
