From their site: Use the Tumblr API to read Tumblr data or to write a Tumblr post. Unlike blogs, tumblelogs aren't designed like a newspaper column. If blogs are journals, tumblelogs are scrapbooks. Blogs are great, but they can be a lot of work. And they're really built to handle longer-form text posts. Tumblelogs, on the other hand, let you easily and quickly post and share anything you find or create, such as photos, videos, audio, quotes, and links, or text.
The following is a list of libraries from ProgrammableWeb's Library Directory that matched your search term. Although there many different interpretations of the word "library" among software developers, ProgrammableWeb adheres to a specific definition so as to clearly distinguish libraries from SDKs and frameworks in a way that will facilitate clean search results. In ProgrammableWeb's parlance, the term "library" is strictly used to describe a platform-specific software tool that, when installed, results in the provisioning a specific API. Conversely, SDKs are exclusively for consuming APIs and Frameworks are agnostic to specific APIs. If you think a library, SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
