MakeUseOf has a clear, simple tutorial for creating feed bundles in Google Reader, including some ideas for presenting the bundles to your community.
Google Reader gives you several ways to share bundles, letting anyone read the aggregated content or subscribe to the feed.? I added a link to our feed bundle in the sidebar of this blog, and can now present a stream of information from NEASIS&T on Twitter and the ASIS&T blog.
I can imagine libraries gathering information for their communities by creating bundles from town websites or academic departments, or promoting the library by creating bundles from internal blogs.
Which feeds would you bundle for your community?? Try it out, and send us your links!
