The resources listed here provide indexing to publications from broad disciplines such as engineering, medicine, chemistry and physics. They employ controlled vocabularies, or subject headings, to organize the material.
Here is a sample list of major content providers for Engineering that Penn Libraries subscribes to. It is by no means a comprehensive list, but these do provide a significant amount of relevant material for NBIC projects. Please see the Engineering Library website for access to additional collections.
These resources index literature from a broad range of disciplines but do not employ controlled vocabularies. They do, however, track citations to and from publications that may be used to find relationships in the literature and as an indicator of a publication's relative importance in a field.
