Any user role that can access the Rialto Marketplace can view DDA-available offers.
If your institution is subscribed to a Demand Driven Acquisition (DDA, the same as Patron Driven Acquisition, PDA) agreement with a platform (see Patron Driven Acquisition), the Rialto Marketplace displays the electronic offers eligible for DDA with the DDA icon by the title.
To enable DDA in Rialto, reach out to ProQuest to configure DDA for your platform(s) of choice.
If an offer is eligible for DDA for any platform, you can include it in your DDA pool for that platform. This means that starting from the moment of inclusion, the platform monitors the usage of this offer by the patrons. Offers that are used in such a way to trigger a purchase (e.g., total number of accesses, downloading the full text, etc.) will be automatically purchased by your library. The specific terms of access and triggers are defined by your DDA agreement with the platform. Until the moment of purchase, while the offer is accumulating the required number of views, the offer is considered to reside in the DDA pool.
For more information, see DDA Guide.
Viewing Offers in the DDA Pool
You can view the list of all titles that participate in the DDA pool on the Demand-Driven Acquisition Pool page (Market > Demand-Driven Acquisition Pool > Demand-Driven Acquisition Pool). This page displays all offers that are active within the DDA pool, meaning offers that patrons can view but which have not yet been purchased.
When DDA has been enabled in Rialto, this page displays all offers in your existing DDA pool(s), including those added manually and automatically via DDA profiles.
Currently, this page does not display offers that were added to DDA pool through other platforms directly. To set up DDA in Rialto, contact ProQuest.
Offers are removed from this list when they become considered as part of the holdings. This can happen due to any of the below reasons:
- The offer has reached its purchase threshold (in terms of downloads, views, or any other activation criteria) and was purchased,
- The offer was purchased via the shopping cart.
You can filter the list to see offers by a particular author, ISBN, Title, or by keywords. You can sort the list by price or publication year.
When the status of the offer is 'Processing', this means that the offer is either in the Shopping Cart (if it appears with the "In Your Cart" / "In Other Carts" badges) or a purchase was already submitted in Rialto.
Removing Offers from a DDA Pool
At present, offers cannot be removed from the DDA pool from within Rialto. An offer that was added mistakenly to the DDA pool may only be removed by contacting the platform directly.
