I'vRead is a record of what books a user has read. Users don't need to sign up for an I'vRead account, they only have to post a Tweet in the format 'book name @ivread comment' and it will update their I'vRead record. Other users can then see lists of what other users have read or lists of popular books. The I'vRead API is a way for developers to integrate I'vRead into their own applications/websites. The API can be used to get JSON or RSS data about Recent Reads or User Information.
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.
