If you want to subscribe to the blog (rather than any other bits of writing and note-taking that go onto the site) go to:
and use the RSS feed there.
The following links will take you to a page: the RSS feed is in the bottom right. Pick the one you want. If you don't want all this goddamn choice to think about, I suggest subscribing to:
Coveredinbees' writing is in one of three categories: academic, 'writing' (i.e. non-academic - so where most blog-style writing will be) and 'gubbins' (usually self-indulgent waffle or attempts at comedy.)
There's also a 'writing star' rating, from one to five. Five stars = I think it's publishable, one star is probably just waffly note-making. Sadly, Drupal can't combine 'AND' and 'OR' in its taxonomy URLs, so if you want only 4 star plus and only academic, you'll have to subscribe to two RSS feeds, and even then you'll still get academic waffle of two stars.
It's the same for any category - so if you only want to know about things tagged international trade, go to that tag and use the bottom right subscribe button. Combine terms with + and , as logical OR and AND respectively. (That is, 11+12 will give you articles from either category whereas 11,12 will only give you articles that include both categories.)
Oh, and if you really want to know when I've added references to the library, here's the library feed...
