SamEnrico sells digital publications and subscriptions. It also provides an OPDS API that allows users to browse, search, and download eBooks, magazines, and papers for free to the e-reader of their choice. It also allows users to display publications on their websites. OPDS (Open Publication Distribution System) is an open standard for creating catalogs for aggregating, distributing, and discovering e-publications by any user, from any source, in any digital format, and on any device.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
