The "paperless office" has never really existed. Even with all sorts of new fangled electronic forms and PDFs (even worse, PDF forms - a horror i sometimes have to build in my day job) there is still a place for paper. There is also still a place for the humble date stamp. It is a simple and effective way to mark... well the date on something, such as documents which have arrived. I had to get one of course, just in case i ever open my own library. It does take a little practice though to get the stamp correct...
