Services and Fees
The APTrust Executive Director proposes fees for all services, with input from the Advisory Committee, and the APTrust Governing Board approves them. Whenever possible, changes in fees are made with sufficient notice to allow members to incorporate them into their regular annual financial planning cycles.
| Service Description | Fee | Details |
|---|---|---|
| Sustaining Membership | $20,000/year | Includes 10 TB storage allowance. |
| High Assurance Storage | $420/year/TB | This fee is assessed per gigabyte of content at $0.41016. |
| Basic Archive Storage | $60/year/TB | This fee is assessed per gigabyte of content at $0.05859. |
| Deep Archive Storage | $20/year/TB | This fee is assessed per gigabyte of content at $0.01953. |
Notes
- APTrust measures preservation storage using the binary calculation method (1 TB equals 1024 GB).
- Storage totals are measured on the first of each month. Annual invoices include a storage report detailing monthly storage usage, including any associates, from April 1 (prior year) to March 31 (current year).
Definitions
Sustaining Member: An APTrust Sustaining Member is an institution that pays an annual Sustaining Membership fee, receives a storage allowance, and plays an active role in the development of the APTrust.
Associate Member: Associate Members are sponsored by Sustaining Members and benefit from APTrust’s preservation infrastructure without committing to a full Sustaining Membership. Their usage is reported and billed to their sponsoring Sustaining Member. Read more in our Associate Member Toolkit.
