Richard Byrne at Free Technology for Teachers recommends 3 Ways To Quickly Share Bunches of Links With Your Students. His resources include:
Bitly is a URL shortener, and you must first sign-in/sign-up in order to use the site. If you use the bookmarklet feature, you can customize URLs, and track statistics about the use of your links. Bitly offers an option for bundling bookmarks into one package that you can share with just one link. Another unique element of Bitly is that the bundles can be created collaboratively if you invite other Bitly users to bundle links with you.
Of the three, Linkbunch has the simplest user-interface. You just list your links in a box and hit “Bunch.” Bundlenut has you go through a series of steps to create your links, but is also relatively easy to use. Here are some sample links created with each site:
Bundlenut – http://www.bundlenut.com/b/854040
Linkbunch – http://linkbun.ch/ndt4
