All Odyssey licenses come with a storage cap for data and digital assets. Additional access storage simply expands the amount of storage available in your regular Odyssey account.
The files that users view within Odyssey or any related public websites are maintained within your account. HistoryIT does not recommend storing archival master TIFF files in an Odyssey account, as they would quickly consume all available storage. To maintain your master files, Odyssey offers Digital Preservation licenses.
Accounts may add additional access tiers to your recurring annual license fees according to the cost schedule below.
