Book Description
Mycology, the study of fungi, originated as a subdiscipline of botany and was a des criptive discipline, largely neglected as an experimental science until the early years of this century. A seminal paper by Blakeslee in 1904 provided evidence for self incompatibility, termed "heterothallism", and stimulated interest in studies related to the control of sexual reproduction in fungi by mating-type specificities. Soon to follow was the demonstration that sexually reproducing fungi exhibit Mendelian inheritance and that it was possible to conduct formal genetic analysis with fungi. The names Burgetf, Kniep and Lindegren are all associated with this early period of fungal genet ics research. These studies and the discovery of penicillin by Fleming, who shared a Nobel Prize in 1945, provided further impetus for experimental research with fungi. Thus began a period of interest in mutation induction and analysis of mutants for biochemical traits. Such fundamental research, conducted largely with Neurospora crassa, led to the one gene: one enzyme hypothesis and to a second Nobel Prize for fungal research awarded to Beadle and Tatum in 1958. Fundamental research in biochemical genetics was extended to other fungi, especially to Saccharomyces cerevisiae, and by the mid-1960s fungal systems were much favored for studies in eukaryotic molecular biology and were soon able to compete with bacterial systems in the molecular arena.

Book Description
Stay up-to-date with the growing amount of reference resources available online How important is the World Wide Web to information retrieval and communication? Important enough that information professionals have seen students exit from their libraries en masse when Internet service was lost. Internet providers dominate the indexing and abstracting of periodical articles as major publishers now offer nearly all of their reference titles in digital form. Libraries spend increasing amounts of funding on electronic reference materials, and librarians devote an increasing amount of time to assisting in their use. The Reference Collection: From the Shelf to the Web is an essential guide to collection development for electronic materials in academic and public libraries. The Reference Collection: From the Shelf to the Web tracks the continuing evolution of electronic reference resources-and how they’re accessed—in a variety of settings. Librarians representing university, elementary school, and public libraries in the United States and Australia examine how reference collections have evolved over time (and may soon be a thing of the past); how public and school libraries have dealt with the changes; why library research assignments have become more difficult for teachers to make and for students to complete; how to organize online reference sources; and why the nature of plagiarism has changed in the electronic era. The book also examines the use of electronic references from a publisher’s perspective and looks at the most important Web-accessible reference tools—both free and subscription—in the areas of humanities, medicine, the social sciences, business, and education. The Reference Collection: From the Shelf to the Web also examines: issues of authority, accessibility, cost, comfort, and user education in evaluating electronic resources the formation of purchasing consortia to facilitate the transfer of reference materials from print to online formats current literature and research findings on the state of digital versus print reference collections what electronic publishing means to smaller reference books (dictionaries, almanacs, etc.) the need for increased information literacy among students the nature, extent, and causes of cyber plagiarism the use of federated search tools and includes a selected list of the top 100 free Internet reference sites The Reference Collection: From the Shelf to the Web is an essential resource for all reference and collection development librarians, and an invaluable aid for publishing professionals.
