Copyright & Credit Information

While IDEA is intended as a free online resource for personal dialect research, IDEA retains copyright on the archive’s files. You may use the archive as such without special permission. However, you may make no hard copy, nor distribute any digital file without the express written consent of IDEA and the payment of a fee appropriate to the intended use.

The following examples are provided as a guide:

For information on the doctrine of fair use, please see the U.S. Copyright Office’s discussion of the topic at
    • Also consistent with fair-use law, you may include brief pieces of information (text and audio) from IDEA in books, articles, papers, training materials, or lectures, without special permission but with proper citation, as required by law. However, you may not include the “native files,” without special permission. If you wish us to provide you with those files, please contact us with full details of your needs. A permissions fee will be assessed, appropriate to the intended use of the files, but sufficient only to cover our administrative costs in the case of non-commercial projects.
    • You may play an IDEA recording or text file in a lecture, class, training session, or workshop directly from the internet, or your students/clients may do so from their own individual internet-connected terminals without obtaining special permission. But distributing copies of files by any other means requires special permission and the payment of an appropriate fee. If you wish to request special permission, or are in doubt about whether your intended use requires it, please email the director, Paul Meier, at

It is fully expected that actors, writers, directors, and others will make use of the archive for research in film and stage productions, though it is requested, as a courtesy, that such use of the archive be acknowledged in the play bill of a theatre production or in the closing credits of a television or feature film as follows:
