Is it a difficult position to be a library clerk?
I wouldn't focus it would be difficult to learn: they'd teach you the system they use for stacking files or CDs; you'd probably be responsible for putting materials clients returned back on shelves, and there're rolling carts that're used for this purpose. Once you swot up where all the section are, if you're working behind the desk, you can help clients find what they're looking for. Every duty has stress, but I don't imagine it would be too stressful contained by the hushed environment of a library, where everyone who comes in pretty much keep to themself. And, if you like books, CDs and magazines, you'll be exposed to lots of materials you can borrow. If you're thinking of taking this nice of job, I would go for it.
Depends on the structure of the library. There is more involved then reshelving of books. There are numerous programs that must be scheduled, forms and paperwork to gratify obligations, tracking down users requests, data entry, handling money.
