Here's an interesting post by Allan Cho, The Future of Digital Librarians. He looks at the issue of skill set needs and LIS education. Here he writes of the difficulty of studying and learning new technologies for on-the-job librarians.
In my own experience as an information professional, I find that these skills are sorely lacking in my own education. I'm finding it increasingly my own initiative to get caught up in the literature and the technologies. Who really has time to learn OAI-PMH metadata standards, XML, EAD, and TEI? Many librarians keep abreast of their field -- but on top of their current duties. But the problem remains that LIS schools do not to train technicians even though that is what they're doing - their mandate is to nurture scholars. Which I can understand. Yet, we can't fit a square peg into a circle. There lies the conundrum: something's got to give. But what? That has remained the intense tension in the field of LIS since its inception. With the advent of the Web and newer technologies, this gap will only widen.
