Scitopia was developed by 21 top technological and scientific societies.  It is a freely available database mainly in physics and engineering.  Component societies are listed on a webpage off www.scitopia.org.  It lists papers going back as early as 1665, some of which are digitized.

Full text is offered on a pay-per-view basis, so currently it is better to search Princeton’s subscription databases which have links to our full-text subscription resources.  INSPEC  and Compendex  cover even more resources than Scitopia.  IEEE  — Xplore & IEL — are other overlapping subscription databases we have, and they are completely full-text.
