Book Description
Plant Breeding Reviews presents state-of-the-art reviews on plant genetics and the breeding of all types of crops by both traditional means and molecular methods. Many of the crops widely grown today stem from a very narrow genetic base; understanding and preserving crop genetic resources is vital to the security of food systems worldwide. The emphasis of the series is on methodology, a fundamental understanding of crop genetics, and applications to major crops. It is a serial title that appears in the form of one or two volumes per year.

Book Description
Silvicultural practices in the Douglas-fir region evolved through a combination of formal research, observation, and practical experience of forest managers and silviculturists, and changing economic and social factors. This process began more than a century ago and still continues. It has had a great influence on the economic well-being of the region and on the present characteristics of the regions forests. This long history is unknown to most of the public, and much of it is unfamiliar to many natural resource specialists outside (and even within) the field of silviculture. We trace the history of how we got where we are today and the contribution of silvicultural research to the evolution of forest practices. We give special attention to the large body of information developed in the first half of the past century that is becoming increasingly unfamiliar to both operational foresters andperhaps more importantlyto those engaged in forestry research. We also discuss some current trends in silviculture and silviculture-related research.

Book Description
Examine crucial issues for audiovisual cataloging-from a variety of perspectives! This vital book addresses both current and historic issues related to audiovisual materials and cataloging. It covers the current cataloging rules for sound recordings (popular music and nonmusic recordings), videorecordings (including DVDs), electronic resources (whether accessed locally or remotely), three-dimensional objects and realia, and kits. Three historical articles chronicle the history of audiovisual catalog in general, the history of cataloging computer files, and the history of The Thesaurus for Graphic Materials. A section on audiovisual materials and subject access issues includes a chapter which proposes form/genre terms for moving-image materials and a special library’s creation and use of a new thesaurus and its availability to assist online catalog users. Finally, four contributions examine audiovisual materials and cataloging from the perspectives of different library types: school, public, academic, and special. The Audiovisual Cataloging Current provides case studies that show: how the National Library of Medicine produces, collects, and catalogs non-print materials the differences between the Moving Image Genre-Form Guide and Library of Congress Subject Headings, with recommendations for improving LCSH as a tool and an exhaustive list of LCSH terms how libraries and organized cataloging groups developed the Chapter 9 descriptive cataloging rules in AACR2 how the Westchester Library System created a user-friendly online catalog for audiovisual materials how the Illinois Fire Service Library improved firefighters’subject access to nonprint fire emergency materials how the National Library of Medicine promotes audiovisual formats and much more!
