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 designated monographs and is the only way to purchase print through Project Euclid. If available, this option will be indicated by a "Purchase print copy" button on the books Table of Contents page. In the future, this may expand to include additional content.
