Abstract
The feeding of documents through optical equipment (such as OCR scanners, microfilming equipment, etc.) is facilitated by providing pocketed document carriers. Each document carrier has a transparent plastic film first part and a white paper second part, with adhesive along some of the edges between the parts defining a pocket, with at least one of the edges open to allow the insertion of one or more documents into the pockets. The carriers, containing the documents, are intermixed in a desired sequence with documents that are full size (e.g., having a size substantially the same as the document carriers) for automatic or hand feeding through the optical equipment. A number of different pocket configurations may be provided, including a duplex construction.
