Currently there is no way to determine the print/download permissions for an eBook before purchasing (aside from those titles indicated as DRM-Free). The Preview function does not include that information. It would be useful for selectors as they make decisions on purchase options, formats, and providers.
Thank you for your comment! In which EBSCO interface -- GOBI or ECM -- are you making eBook purchases? In ECM, for an eBook we do display the publisher's print/download/copy/paste permissions, and we display them at the business model as well (e.g. if an eBook is available as a 1U and DRM-free UU, you can see the corresponding set of permissions when you select the specific model).
