Antony Groves has published "Using Vine to Disseminate Library Information: A Practical Guide" in the LSE Impact Blog.
Here's an excerpt:
There are a number of blog posts recommending Vine to librarians, featuring some excellent examples of how the app is being used by libraries . . . Despite this, Vine remains an under-used tool. One reason for this may be the absence of a clear guide on how to use Vine. The following article intends to address this issue by equipping practitioners with a short guide to creating Vines. It will begin by introducing Vine, explaining what it is and why it should be considered when promoting certain aspects of the Library. This will be followed by a five-step guide to creating Vines on Android devices and iPhones.
