Pay-per-view and print-on-demand
If access to full text is denied (no subscription), publishers may choose to offer a pay-per-view (PPV) option. This allows non-subscribers to purchase immediate access on an article-by-article basis at a price set by the publisher. This option will be indicated by a "Buy article" button.
Project Euclid currently offers print-on-demand (POD) services for select content through outside vendors. This service is only available for certain titles and is the only way to purchase print copies through Project Euclid. If available, this option will be indicated by a "Purchase print copy" button on the title's Table of Contents page. Over time, this service will expand to include additional content.
