Some data may be accessed by any interested user. Other data may only be accessed by authorised academic users. Any researcher wishing to use the MTUS data should register as an MTUS user by completing the registration form, and apply to the original data producers for permission to use the restricted data sets.
The MTUS is a collaborative project, and as a condition for receiving the data for free, all registered users undertake to give back to the project any improved or enhanced data files as well as the citations of publications they produce using the MTUS data. Also, all registered users must agree not to give any MTUS data to any third party.
Each researcher proposing to use any element of data connected with the MTUS needs to apply separately for permission to use the data. Research assistants are covered by agreements signed by lead researchers.
The main MTUS data file includes aggregated data. There are two levels of aggregate data available:
In many cases, the MTUS co-ordinators also have the original episode data files on which the MTUS aggregated file is based. At this time, researchers can gain access to any Class A country episode file for data collected in the 1980s or earlier by submitting a separate request to the MTUS User Team. Permission to use more recent Class A sequence files may require permission from the data depositor. We are in the process of producing the formal table of access requirements for this data at this time. Permission to use sequence data from a Class B country should be requested from the data producer directly.
