The Harvard University Library has worked closely with a vast array of information technology specialists and others to craft this fine collection of research guides. From African Studies to Zoology, each guide contains information culled from both print resources at Harvard's libraries to a plethora of digital resources from around the Internet. There are a number of particularly rich guides here, including those for Data and Biological Sciences. Visitors can learn about each resource in detail, including when they were last updated and other salient details. One can imagine that given the breadth of these guides, they might be used in a variety of educational settings from high school to post-graduate studies.
