Librarians, Jelly Beans, and Google Book Search

摘要

Until relatively recently, researchers needed to mem -orize or tediously record the key resources and places within sources that held valuable information vital to their work. Reference librarians made mental notes or kept card files of vital resources on a wide range of topics and of key sources for specialized information. Finding which works had been published with content on a topic was a slow and unsure process with duplication of effort as the work of others in the same topic area was often undiscoverable.
