While an Overton Index trial is a great way to get familiar with the platform’s functionality, features and our data, there are a few limitations on trial accounts.
This article provides an overview of trial account limitations.
Searching with DOIs and other identifiers
If you are searching the Policy Documents tab or the Scholarly Articles tab using a list of DOIs or other identifiers, you will be able to search for a maximum of 1000 identifiers at one time. Full-access accounts allow users to search using up to 25,000 identifiers.
Viewing & exploring results
When you have a list of search results, as a trial user you will be able to access and explore the first 3 pages of results. This will still give trial users a good overview of what results they can expect.

Exporting policy document results
If you would like to export Policy Document results, you will be able to export the top 60 records into either Excel, RIS or CSV formats.

Exporting scholarly article results
If you would like to export Scholarly article results, you will be able to export 150 records into either CSV or RIS format.

Continuing Access
Once your trial account expires, you will still have access to the basic features of Overton Engage.
For continued access to Overton Index, please contact your organisation’s library or research office to discuss a subscription. If institutional funding is unavailable, you might consider our Academic Supporter Plan.
