At my place of work, a major University library, there are many people who have an affinity with the written word. For some this may result in a very useful specialisation which benefits their careers within information sciences. For others, and I magnanimously include myself, working in a library is a way to be around books while we dream and hopefully work towards being a writer of some description ourselves.
I have lots of colleagues who write poetry, sci-fi novels, non-fiction, articles and so on. From that point of view it is a nice working circle but I when I get slightly disheartened I sometimes wonder whether we'd all rather be doing something else.
