A portable flatbed scanner with one transparent platen facing the original document and another transparent platen at the back of the housing for the scanning mechanism. The original document is placed face up, but the portable flatbed scanner is placed face down on the original document, and the user can see the original document through the two transparent platens. Therefore, the effect of "what you see is what you scan" is achieved. As a result, the scanning area can be set without a prescan and the portable flatbed scanner can be used as a standalone scanner. Bibliographic information can be associated with a scanned image.
