For public and school libraries, this resource reflects recent changes in Library of Congress subject headings and authority files, and provides bilingual information essential to reference librarians and catalogers serving Spanish speakers. Libraries must provide better access to their collections for all users, including Spanish-language materials. The American Library Association has recognized this increasing need. Subject Headings for School and Public Libraries: Bilingual Fourth Edition is the only resource available that provides both authorized and reference entries in English and Spanish. A first-check source for the most frequently used headings needed in school and public libraries, this book incorporates thousands of new and revised entries to assist in applying LCSH and CSH headings. Of the approximately 30,000 headings listed, most include cross-references, and all of the cross-reference terms are translated. MARC21 tags are included for all authorized entries to simplify entering them into computerized catalogs, while indexes to all headings and free-floating subdivisions are provided in translation from Spanish to English. This book gives librarians access to accurate translations of the subject terms printed in books published and cataloged in English-speaking countries—invaluable information in settings with Spanish-speaking patrons.

Although cacti such as the saguaro and organ pipe have come to define the Sonoran Desert for many people, they represent some 170 species of columnar cacti found in many parts of the Americas. These giant plants are so dominant in some ecosystems that many species of animals rely on them for food and shelter. They are pollinated by bats in central Mexico and Venezuela, by birds and bees in northern Mexico and Peru. This book summarizes our knowledge about the ecology, evolution, and conservation of columnar cacti and their vertebrate mutualists to show that the very survival of these cacti depends on animals who pollinate them and disperse their seeds. Contributors from the United States, Mexico, Venezuela, and Colombia explore aspects of geology and evolution that have forged this relationship, review findings in anatomy and physiology, and discuss recent research in population and community ecology as well as conservation issues. Ranging from the Sonoran Desert to the northern Andes, these studies reflect progress in understanding how abiotic and biotic factors interact to influence the evolution, distribution, and abundance of cacti and mutualists alike. In addition, this book examines the ways in which humans, through the process of domestication, have modified these plants for economic benefit. The contributors also review phylogenetic relationships between cacti and nectar-feeding bats in an effort to understand how bat-plant interactions have influenced the evolution of diversity and ecological specialization of both. Because of the number of migratory pollinators feeding on columnar cacti, the authors make conservation recommendations aimed at preserving fully functional ecosystems in arid portions of the New World tropics and subtropics. Columnar Cacti and Their Mutualists provided a benchmark for both conservation efforts and future research.

Build better readers in bilingual classrooms! Bilingual Reading Comprehension is a valuable resource for bilingual, two-way immersion in fifth-grade classrooms. This book provides bilingual reading practice for students through identical activities featured in English and Spanish, allowing the teacher to tailor lessons to a dual-language classroom. Fiction and nonfiction activities reinforce essential reading skills, such as finding the main idea, identifying supporting details, recognizing story elements, and learning new vocabulary. This 160-page book aligns with Common Core State Standards, as well as state and national standards.

A guide to books in Spanish published since 1982.
