Considering the way to discover information often distinguished two different ways: search and exploration.

Following the model of Google, the search has become almost the only way of discovery, although exploration is increasingly receiving more attention. A way of exploring indexes belong classics library catalogs and also from this point, the Virtual Library of CSIC (http://tinyurl.com/hpn3hr3) introduces a new form of exploration by tracking items They cite or are cited by another article.

From now in many search results Virtual Library legends "Quotes" and "Quoted by" which allow, with a single click to see the articles that are cited by the article in question or cite this appear, and thus follow a path of exploration on a given topic. We hope this new tool will be useful for users of the Virtual Library.
