I probably missed this since I don’t typically pay much attention to Merlot, but Merlot looks like it finally has RSS feeds for arbritary searches and categories now (e.g. literature). It could do with a little polish, e.g. putting the search or category in the RSS feed title, and fixing the spelling of “materials”. Also, when I did a sort, it appeared to be in reverse order, although I’m less clear on how the RSS feed itself behaves – it appears to not keep track of the keywords or category.
A good step in the right direction though.
