Fees

As a nonprofit endeavor, Shared Shelf seeks to generate sufficient revenue to cover the ongoing operational cost of hosting institutional content and sustaining the maintenance and development of the Shared Shelf infrastructure.

The Shared Shelf fee structure combines two annual fees: an Institutional Classification Base Fee and a Service Fee based on the number of digital assets* stored in the system. The fee structure aims to be fair to subscribing campuses by scaling fees to both campus size and utilization of the system.

Shared Shelf is intended to serve as a richly functional repository for the use and management of images. It will provide a cataloging platform; tools for contributing to and using a controlled vocabulary warehouse; the ability to seamlessly host high-quality images derived from your master copy; and functionality for exporting these derivative images and data records for use in the ARTstor Digital Library web environment, other websites, or local programs. Over the next three years, we will work together with the community to determine whether expanding Shared Shelf to serve as a preservation repository for master image files would be desirable. During that time, we will also be exploring the extent to which it would be desirable to expand the service to video and audio files.


Fee structure overview

Institutional Classification Base Fees

Institutional Classification Annual Fee
Very Large I $13,000

Service Fees

Number of Assets* Service Fees Per Asset*
5,000 $0.00
5,001 – 50,000 $0.23
50,001 – 200,000 $0.21
200,001 – 260,000 $0.18

* An asset is defined as a source image file (e.g., TIFF, JPG, GIF, PNG, etc.) with one or more corresponding data records.



Maximum Annual Fees

The purpose of asset-based service fees is to recoup storage, related infrastructure, and staff costs to sustain the Shared Shelf platform. However, if allowed to continually accrue, the service fees would begin to over-recover cost. As a non-profit initiative, this is not the goal of Shared Shelf. Thus, annual fees will be capped at a maximum level that is scaled based on classification of institution. The maximum annual fees include the base fee plus asset-based service fees, and once reached, asset-based service fees will no longer accrue. Institutions would only be required to pay their maximum annual fee regardless of the number of images stored in the system.*
