图书馆按需打印的实践与未来 总被引：1，自引：0，他引：1
按需打印是出版行业的一次革命性变革,它使出版的形态发生变化,将对图书馆的未来发展产生重要影响。对于读者服务来说,自动印书机(EBM)的打印目录数据库增加了读者获取文献的渠道,其运用使读者能够根据需要自我汇编图书并打印。对于图书馆文献收藏策略来说,EBM+PDA模式将图书馆员从以往的揣测式采访的困境中解脱出来,使购买的文献就是真正流通的文献。但EBM存在价格昂贵、作者和出版商认可程度不高、没有配套适用的著作权法及相关法律等问题。 相似文献

Children's literacy skills are an important predictor of success in the early elementary grades. Education programs for at-risk preschool students target children's acquisition of specific literacy skills, including knowledge of letters of the alphabet, in preparing children for early school success. Writing has been proposed as a complementary approach to other instructional strategies for teaching young children about letters. This study examines relations among preschool children's early writing competence, knowledge of letter names, sensitivity to initial sounds in words and understanding of print concepts in a sample of low-income children enrolled in Head Start. Data were collected from the beginning to the end of the school year, which offered the opportunity to examine concurrent development of these early literacy skills. Results revealed that children whose writing was more sophisticated knew the names of more letters, understood more about print concepts and were more sensitive to initial sounds of words. There was evidence of bidirectional influences of writing on growth in letter knowledge, and of letter knowledge on growth in writing competence. 相似文献
