Office of Science Alerts

Welcome to SC Alerts

The Office of Science SC Alerts service is like having an expert personal research assistant who searches the Internet for science topics of your special interest and delivers to you—every week—a neat, comprehensive list of the most current preprint titles about those topics with direct web links to full-text articles.

SC Alerts is a customized service developed by the Office of Scientific and Technical Information (OSTI) for the Office of Science. It allows users to create one or more personal interest profiles, which OSTI's E-print Network search engines will use to compile lists of preprint articles that contain key words and ideas of the users' stated interests. Then, the E-print Network will notify individual users by e-mail on a weekly schedule whenever documents matching your search terms are indexed or added to the Deep Web selected databases. This Alert Service can also be utilized to automatically receive notification of new e-prints emanating from particular laboratories.

SC Alerts is the first alerting service that harvests information from the deep web, where the underlying content of selected web sites and databases is searched rather than only surface pages of web sites. The SC Alerts service is free, and in most cases, access to the full-text information is open and free of charge.

Preprints are manuscripts disclosing research progress so new that it has not yet been published. Preprints may or may not have been reviewed, submitted, or accepted for publication but are intended for publication or presentation at a conference and are being circulated for comment. Some preprint servers may define preprints as any electronic work circulated by the author outside of the traditional publishing environment.

The E-print Network, the power that operates the SC Alerts service, is a searchable gateway to over 12,000 Web sites and databases worldwide, containing e-prints in basic and applied sciences, primarily in physics but also including subject areas such as chemistry, biology and life sciences, materials science, nuclear sciences and engineering, energy research, computer and information technologies, and other disciplines of interest to DOE. The E-print Network's other resources include academic institutions, government research laboratories, scientific societies, private research organizations, and the holdings of individual scientists and researchers.

Register as a First-time User

Then create a search strategy with your personal science interests—the SC Alerts Help feature will explain how to do it. Your search strategy will then be matched automatically against each new weekly update of all the servers within the E-Print Network and notification will be sent by e-mail stating the number of preprint sources awaiting your retrieval on the SC Alerts web page.

Search Tips


The Office of Scientific and Technical Information has developed products in three areas in which researchers communicate their findings: E-Print Network for preprints; DOE Information Bridge for technical reports or gray literature; and Energy Citations for bibliographic citations of DOE research from 1948 to today.
