PTSDpubs (Formerly PILOTS)Created by the National Center for PTSD, this database - formerly known as PILOTS - provides citations to all kinds of literature involving PTSD and traumatic stress.
This database is an electronic index to the worldwide literature on PTSD and other mental health consequences of exposure to traumatic events. Unlike other databases, PTSDpubs does not restrict its coverage to articles appearing in selected journals. It attempts to include all publications relevant to PTSD and other forms of traumatic stress, whatever their origin without disciplinary, linguistic, or geographic limitations.
PTSDpubs is produced by the National Center for PTSD, and is electronically available to the public. There is no charge for using the database, and no account or password is required. Although it is sponsored by the U.S. Department of Veterans Affairs, the PTSDpubs database is not limited to literature on PTSD among Veterans.
