Pay-Per-View Purchase and Refund Policy

Some publishers sell individual articles on a pay-per-view basis. If this option is available, it is activated by selecting the "Buy Article" button on an article abstract page.

If you select this option, we will obtain an authorization from your credit card issuer. Once credit card authorization has been received, you will receive access to your downloadable article. Downloadable articles are non-refundable. If you do not receive your article after being charged, contact us and we will supply you with an electronic copy of the article by email.

If you have any questions about pay-per-view, please contact Euclid.
