“No! We can’t rid of that!” Vnuk, author of the popular “Weeding Tips” column on Booklist Online, is here to show you that yes, you can. A library is an ever-changing organism; when done the right way, weeding helps a library thrive by focusing its resources on those parts of the collection that are the most useful to its users. Her handbook takes the guesswork out of this delicate but necessary process, giving public and school library staff the knowledge and the confidence to effectively weed any collection, of any size. Going through the proverbial stacks shelf by shelf, Vnuk Explains why weeding is important for a healthy library, demonstrating that a vibrant collection leads to robust circulation, which in turn affects library budgetsWalks readers through a library’s shelves by Dewey area, with recommended weeding criteria and call-outs in each area for the different considerations of large collections and smaller collectionsFeatures a chapter addressing reference, media, magazines and newspapers, e-books, and other special materialsShows how a solid collection development plan uses weeding as an ongoing process, making it less stressful and more productiveOffers guidance for determining how to delegate responsibility for weeding, plus pointers for getting experienced staff on boardGives advice for educating the community about the process, how to head off PR disasters, and what to do with weeded materialsIncludes a dozen sample collection development plans, easily adaptable to suit a library’s individual needsFilled with field-tested, no nonsense strategies, this handbook will enable libraries to bloom by maintaining a collection that users actually use.

E-book content, devices, and services have created challenges for libraries as well as opportunities. Because the e-book playing field is constantly changing, any predictions are, at best, tenuous. Librarians must be resilient in order to manage, and not be managed by, e-books and their progenies. With their explosive sales and widespread availability over the past few years, e-books have definitively proven that they are here to stay. In this sequel to her first book of the same title, the author dives even deeper into the world of digital distribution. Contributors from across the e-book world offer their perspectives on what is happening now and what to expect in the coming months and years. Included in this resource are: Guidelines for performing traditional library processes such as cataloging, weeding, archiving, and managing e-book accessibility for patrons with special needs; Explorations of topics such as the e-book digital divide and open-access publishing; Case studies from an array of academic, public, and school libraries, offering firsthand accounts of what works, what doesn't, and why; Discussions of the emerging model of the electronic-only library and the rich possibilities of enhanced e-books.

At Clay Bottom Farm, author Ben Hartman and staff practice kaizen, or continuous improvement, cutting out more waste--of time, labor, space, money, and more--every year and aligning their organic production more tightly with customer demand. Applied alongside other lean principles originally developed by the Japanese auto industry, the end result has been increased profits and less work. In this field-guide companion to his award-winning first book, The Lean Farm, Hartman shows market vegetable growers in even more detail how Clay Bottom Farm implements lean thinking in every area of their work, including using kanbans, or replacement signals, to maximize land use; germination chambers to reduce defect waste; and right-sized machinery to save money and labor and increase efficiency. From finding land and assessing infrastructure needs to selling perfect produce at the farmers market, The Lean Farm Guide to Growing Vegetables digs deeper into specific, tested methods for waste-free farming that not only help farmers become more successful but make the work more enjoyable. These methods include: Using Japanese paper pot transplanters Building your own germinating chambers Leaning up your greenhouse Making and applying simple composts Using lean techniques for pest and weed control Creating Heijunka, or load-leveling calendars for efficient planning Farming is not static, and improvement requires constant change. The Lean Farm Guide to Growing Vegetables offers strategies for farmers to stay flexible and profitable even in the face of changing weather and markets. Much more than a simple exercise in cost-cutting, lean farming is about growing better, not cheaper, food--the food your customers want.

Non-Chemical Weed Control is the first book to present an overview of plant crop protection against non-food plants using non-chemical means. Plants growing wild—particularly unwanted plants found in cultivated ground to the exclusion of the desired crop—have been treated with herbicides and chemical treatments in the past. As concern over environmental, food and consumer safety increases, research has turned to alternatives, including the use of cover crops, thermal treatments and biotechnology to reduce and eliminate unwanted plants. This book provides insight into existing and emerging alternative crop protection methods and includes lessons learned from past methodologies. As crop production resources decline while consumer concerns over safety increase, the effective control of weeds is imperative to insure the maximum possible levels of soil, sunlight and nutrients reach the crop plants. - Allows reader to identify the most appropriate solution based on their individual use or case - Provides researchers, students and growers with current concepts regarding the use of modern, environment-friendly weed control techniques - Presents methods of weed management—an important part of integrated weed management in the future - Exploits the knowledge gained from past sustainable weed management efforts

This guide has been developed for extension officers in both the public and the private, including those interested in agricultural development in Zambia. The goal of this manual is to serve as a tool that allows readers to access up to date information about various agricultural practices and their advantages and disadvantages. There are many organisations in Zambia that have programs that aim towards sustainable development in the agricultural sector. Amongst these programs, there are many different approaches to the goal of improving livelihoods. Although these various programs have good reasons for promoting their specific methods, this manual aims to take an independent stance to portray what all of them offer and why. This manual also includes significant information about new approaches and traditional farmer practices or conventional farming methods. The central theme in this manual is that there can never be only one way to achieve a goal under such diverse conditions as are found in agriculture. Although a certain amount of benefit can be gained by rigid guidelines to agricultural practice (for example a specific crop spacing, tillage method or fertilizer recommendation), the diverse factors that affect peoples’ decisions relate to economic, social and environmental conditions make such guidelines impractical in many cases.
