## Abstract

Placing sheets around a retainer or between a retainer and clamp and securing a clamp against the sheets and retainer for compressively fixing the pages against the retainer.

## Claims

### Claim 1

A method for using a binder clip to bind a plurality of media sheets, comprising:
providing an elongated clamp having a first bottom surface, a pair of sidewalls substantially coextensive with the first bottom surface, and a second bottom surface, wherein the pair of sidewalls are each integrally formed with the first bottom surface, the pair of sidewalls converging toward each other at a top opening of the elongated clamp and each including an elongated top edge, wherein the two elongated top edges are flexibly biased toward each other, and wherein the second bottom surface is coextensive with the first bottom surface and integrally formed with the first bottom surface and with one of the sidewalls and at an angle with the first bottom surface;
providing an elongated retainer having a first substantially flat surface along a lengthwise direction of the retainer, wherein the first substantially flat surface substantially faces the first bottom surface, and a second substantially flat surface that substantially faces the second bottom surface;
wrapping a plurality of media sheets around the elongated retainer;
disposing the elongated retainer and the wrapped sheets in a space between the sidewalls and the bottom surfaces, the first substantially flat surface facing the first bottom surface; and
securing the plurality of media sheets between the sidewalls and the elongated retainer via a compressive biasing force of the sidewalls and elongated edges towards the retainer.

### Claim 2 (depends on 1)

The method of claim 1, further comprising providing a flange at one end of the elongated retainer for preventing the elongated retainer from sliding away from the integrally formed sidewalls and the first bottom surface.

### Claim 3 (depends on 1)

The method of claim 1, further comprising disposing photographic images on one side of each media sheet.

### Claim 4 (depends on 1)

The method of claim 1, further comprising disposing photographic images on both sides of each media sheet.

### Claim 5 (depends on 1)

The method of claim 1, further comprising disposing a flange on each end of the retainer.

### Claim 6 (depends on 1)

The method of claim 1, wherein the clamp comprises an elongated shape at least about 80% of the length of the retainer.
