Hyperlink the repositories?
e.g. MERLOT, OER Commons and ARIADNE.
For this section it will probably be useful for the readers.
There is a risk of ending up with too many links on the page. Should we hyperlink general search engines and general repositories (e.g. Google, Yahoo, Flickr, YouTube, etc.)?
I added hyperlinks to the mention of MERLOT, OER Commons ADRIANE. I haven't added Google or Yahoo because I feel they are covered sufficiently by the Creative Commons Search (even though there can be problems with the back button), though I could see adding them as a stand alone entry.
Flickr is placed as a general repository, not as a search engine because search results are restricted to a single domain. YouTube has been added to the All Rights Reserved repository appendix for the same reasons.
