    4. "GTD representatives" denotes any senior management staff of START, and any employee or representative of said organization whom senior management staff designate to represent START in dealings with the USER.

  2. Usage Rights: Pursuant to this agreement, START grants the USER the non-exclusive, non-guaranteed right to search, browse, and view all contents in the GTD World Wide Web interface.

  3. Authorship: All contents of the GTD were assembled by representatives of START and do not purport to reflect the official position or data collections of the Department of Homeland Security or any other agency of the United States government.

  4. Acknowledgement: All information sourced from the GTD should be acknowledged by the USER and cited as follows: "National Consortium for the Study of Terrorism and Responses to Terrorism (START). (2017). Global Terrorism Database [Data file]. Retrieved from https://www.start.umd.edu/gtd"

  5. Unauthorized Reconstruction of the Data: The GTD website allows the USER to download the entire GTD dataset in a portable file format through the Download page. In addition, the GTD's World Wide Web interface allows the USER to download information on up to 1000 incidents at a time. However, the USER is not permitted to use this feature or any other method to reconstruct the original data set upon which the GTD interface is based. This includes the compilation of more than 1000 incidents from the GTD interface by either manual or automated methods.

  6. Unauthorized Publication of the Data: No part of the GTD may be republished on any website or accessible for public download in any format without the express permission of a GTD staff member. In addition, no part of the GTD may be distributed for any commercial purpose, nor with the intent that the data be used in any commercial enterprise, without the express permission of a GTD staff member. START reserves the right to withhold this permission.

  7. Penalties: Penalties for failure to comply with the terms of this agreement may result in loss of access to the GTD and the forfeiture of user privileges, in addition to any other appropriate legal remedies.

  8. Limitation of Liability: Limitation of Liability: Although every reasonable effort has been made to check sources and verify facts, START cannot guarantee that accounts reported in the open literature are complete and accurate. START shall not be held liable for any loss or damage caused by errors or omissions or resulting from any use, misuse, or alteration of GTD data by the USER. The USER should not infer any additional actions or results beyond what is presented in a GTD entry and specifically, the USER should not infer an individual associated with a particular incident was tried and convicted of terrorism or any other criminal offense. If new documentation about an event becomes available, an entry may be modified, as necessary and appropriate.

  9. Multimedia Copyright: Images and other multimedia files contained in the GTD are held under copyright to various parties. No multimedia files from the GTD may be removed, reproduced, or disseminated without express written permission from the copyright holder.

  10. Termination of Rights: The GTD developers reserve the right to remove access from any particular IP address or set of IP addresses, or to remove the database entirely from public access, at their discretion. In such an event, all USER rights granted in this document are terminated.
