Abstract

Physical documents may be edge marked and the edge markings used to index and retrieve them from their storage locations. A method of managing a physical document, wherein the physical document includes at least one sheet of material, includes marking an edge of the at least one sheet of material with indicia arranged to form a code identifying the sheet of material, storing the physical document in a storage location, indexing the physical document by associating the code with the storage location, and storing the indexing information in a computer-based information retrieval system. A method of retrieving a physical document stored in a storage location, includes obtaining a code associated with the physical document, wherein the physical document includes at least one sheet of material having a first surface, a second surface disposed opposite the first surface and an edge extending between the first surface and the second surface and peripherally about the sheet of material, the edge having indicia arranged thereon to form the code identifying the sheet of material, and information recorded on at least one of the first and second surfaces of at least one of the sheets of material, using a scanning device to scan the storage location for the code, and when the output of the scanning device indicates the location of the code, retrieving the physical document.

Claims

1. A method of managing a physical document, wherein the physical document includes at least one sheet of material, comprising:

marking an edge of at least one sheet of material with indicia arranged to form a code identifying the sheet of material;

storing the physical document in a storage location;

taking an image of the physical document'"'"'s location;

indexing the physical document by associating the edge code with the storage location and the image of the document'"'"'s location, and

storing the indexing information and the image of the document'"'"'s location in a computer-based information retrieval system.

2. The method of claim 1, wherein the at least one sheet of material includes a first surface, a second surface disposed opposite the first surface and an edge extending between the first surface and the second surface and peripherally about the sheet of material and information recorded on at least one of the first and second surfaces of the at least one sheet of material.

3. The method of claim 2, wherein the edge code is pre-marked during fabrication of the sheet of material and before information is recorded on the surface.

4. The method of claim 1, wherein the edge code comprises a unique code.

5. The method of claim 1, wherein the edge code comprises a code 64 bits long.

6. The method of claim 1, wherein the physical document includes additional sheets of material.

7. The method of claim 2, wherein the recorded information is associated with a digital file indexed in the information retrieval system.

8. The method of claim 7, wherein the edge code is associated with the recorded information in the information retrieval system.

9. The method of claim 1, further comprising:

scanning the storage location for a second edge code associated with a second physical document; and

upon locating the second edge code, indexing the second edge code and the location of the second physical document in the storage location in the computer-based information retrieval system.

10. The method of claim of claim 1, further comprising:

finding in the computer-based information retrieval system a second edge code associated with a second physical document indexed therein;

determining the storage location of the second physical document from the storage location information associated with the second physical document and

retrieving the second physical document from the determined storage location.

11. A method of retrieving a physical document stored in a storage location, comprising:

obtaining a code associated with the physical document, wherein any location information associated with the physical document is insufficient to enable retrieval of the physical document from the storage location;

wherein the physical document includes at least one sheet of material having a first surface, a second surface disposed opposite the first surface and an edge extending between the first surface and the second surface and peripherally about the sheet of material, the edge having indicia arranged thereon to form the code identifying the sheet of material and information recorded on at least one of the first and second surfaces of at least one of the sheets of material;

using a scanning device to scan the storage location for edge codes; and

when the output of the scanning device indicates the location of the desired edge code, retrieving the physical document from the indicated location.

12. The method of claim 11, further comprising:

taking an image of the physical document'"'"'s location;

indexing The location of the physical document by associating the code with the storage location and the image of the document'"'"'s location; and

storing the indexing information and the image of the document'"'"'s location in a computer-based information retrieval system.

13. The method of claim 11, wherein the code comprises a unique code.

14. The method of claim 11, wherein the code comprises a code 64 bits long.

15. The method of claim 11, wherein the physical document includes additional sheets of material.

16. The method of claim 11, wherein the obtaining step includes searching an index of indexed physical documents in an information retrieval system.
