What to do after submitting a data request
Repository agreement
Researchers are asked to sign a repository agreement that is tailored to the specifics of their data request.
This agreement identifies the grants that you should include in the acknowledgements section of your publication.
You will be sent a repository agreement after you submit a data request.
Why acknowledgement is important
Many researchers, together with their staff and financial supporters, helped create these datasets and data dictionaries.
By acknowledging their past work in your publication you are:
- Recognizing their efforts
- Ensuring they get funding for future research
- Helping research teams continue to share data
Notify us about your publication
Once your publication has been accepted for publication:
- Please provide Oregon Alzheimer's Disease Research Center (OADRC) with a final copy of your manuscript
- Please upload the final copy to PubMed Central, in accordance with NIH public access policy
