Stand alone handheld scanner?

[webjourneyman]

To help me do research I´m searching for a stand alone handheld scanner I can take with me to libraries and scan text from books/magazines, save and later load into and read on my computer. The only ones I´ve found either require me to bring a labtop along or only scan one line at a time (so called pen scanners), do you know about some gadget that resembles my description?
