There doesn't seem to be a lot out there on the background and development of education for librarianship (a word that Blogger's spellchecker doesn't recognize, by the way), though admittedly I've only just started looking.
This was inspired by two things: I recently finished and submitted a review of a book on the history of information professions in Britain, and I have a question that has been a source of longstanding puzzlement: why do we get Master's degrees, anyway?
As it turns out, that's a fairly complex question, even though the Master's degree in Library Science is a relatively recent development. Its facets include the nature of education for the professions in general, the professional status of librarianship itself, the longstanding and occasionally acrimonious split between librarianship and information science, the gendering of the profession, and, of course, politics. You can't get human endeavor without also getting politics.
Accordingly, this might be a bit much for a blog post, or a series of blog posts. For the nonce, however, this is where my thoughts on the subject will appear. More to come.
