Book Description
This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1902 Excerpt: ...earth. r' = radius of moon, or other body. P = moon's horizontal parallax = earth's angular semidiameter as seen from the moon. f = moon's angular semidiameter. Now = P (in circular measure), r'-r = r (in circular measure);.'. r: r':: P: P', or (radius of earth): (radios of moon):: (moon's parallax): (moon's semidiameter). Examples. 1. Taking the moon's horizontal parallax as 57', and its angular diameter as 32', find its radius in miles, assuming the earth's radius to be 4000 miles. Here moon's semidiameter = 16';.-. 4000::: 57': 16';.-. r = 400 16 = 1123 miles. 2. The sun's horizontal parallax being 8"8, and his angular diameter 32V find his diameter in miles. ' Am. 872,727 miles. 3. The synodic period of Venus being 584 days, find the angle gained in each minute of time on the earth round the sun as centre. Am. l"-54 per minute. 4. Find the angular velocity with which Venus crosses the sun's disc, assuming the distances of Venus and the earth from the sun are as 7 to 10, as given by Bode's Law. Since (fig. 50) S V: VA:: 7: 3. But Srhas a relative angular velocity round the sun of l"-54 per minute (see Example 3); therefore, the relative angular velocity of A V round A is greater than this in the ratio of 7: 3, which gives an approximate result of 3"-6 per minute, the true rate being about 4" per minute. Annual ParaUax. 95. We have already seen that no displacement of the observer due to a change of position on the earth's surface could apparently affect the direction of a fixed star. However, as the earth in its annual motion describes an orbit of about 92 million miles radius round the sun, the different positions in space from which an observer views the fixed stars from time to time throughout the year must be separated ...

Book Description
Pomologist William Coxe (1762-1831) is considered to be one of the foremost fruit growers in America. At his home in Burlington, NJ, he experimented with new varieties of fruits, many based on the specimens he collected both in the United States and abroad. This 1817 work is considered by many to be the authoritative work on fruit culture of the colonial and revolutionary periods.

Book Description
Innovations in library services are rapidly developing within numerous areas including building design, program and event planning, patron experience and engagement, literacy program development, and administration and management. To ensure these changes are implemented and considered successfully, a closer look at the challenges, trends, and practices of these innovations is crucial. Technological Advancements in Library Service Innovation examines the recent activities of successful and groundbreaking research and practices around the world surrounding library service innovation and presents various forward-thinking initiatives. It also provides an overview of libraries’ successful experiences, identifies emerging global themes and trends, and offers guidance to library practitioners on how to pursue the recent trends in their own library environment. Covering topics such as technology adoption and organizational structures, this book is ideal for library professionals, researchers, academicians, instructors, and students.

Book Description
"ARL has published a book and Web site profiling selected rare and special collections in major research libraries of North America, Celebrating Research: Rare and Special Collections from the Membership of the Association of Research Libraries. The compendium is a sampling of the abundance and variety of collections available for use. Special collections have been broadly construed to encompass distinctive, rare and unique, emerging media, born-digital, digitized, uncommon, non-standard, primary, and heritage materials. Celebrating Research includes 118 collection profiles, each from a different ARL member library. Each profile is illustrated with color photographs and tells a story of a single collection, recounting how the resources were acquired and developed. The compilation is rich with examples of how research libraries are engaging different communities to deliver library services and encourage the use of such distinctive collections. Also included is an introductory essay by British rare book expert Nicolas Barker and an appendix that provides a broad description of each library's special collection holdings and pertinent contact information. The book contains a detailed index; the Web site provides a search engine. The volume is the result of a collaborative effort among ARL member libraries on the occasion of the Association's 75th anniversary. It was edited by Philip N. Cronenwett, Special Collections Librarian Emeritus, Dartmouth College Library; Kevin Osborn, Research & Design Ltd.; and Samuel A. Streit, Director for Special Collections, Brown University Library."--Publisher's website.

Book Description
A book that became an instant classic when it first appeared in 1995, Old Southern Apples is an indispensable reference for fruit lovers everywhere, especially those who live in the southern United States. Out of print for several years, this newly revised and expanded edition now features descriptions of some 1,800 apple varieties that either originated in the South or were widely grown there before 1928. Author Lee Calhoun was one of the foremost figures in apple conservation in America. This masterwork reflects his knowledge and personal experience over more than thirty years, as he sought out and grew hundreds of classic apples, including both legendary varieties (like Nickajack and Magnum Bonum) and little-known ones (like Buff and Cullasaga). Representing our common orchard heritage, many of these apples are today at risk of disappearing from our national table. Illustrated with more than 120 color images of classic apples from the National Agricultural Library’s collection of watercolor paintings, Old Southern Apples is a fascinating and beautiful reference and gift book. In addition to A-to-Z descriptions of apple varieties, both extant and extinct, Calhoun provides a brief history of apple culture in the South, and includes practical information on growing apples and on their traditional uses.
