[Update]: This post is quite old and you should now be using the excellent Font Awesome.

In a few projects I use the excellent Twitter Bootstrap. This comes with the equally excellent (and free) Glyphicons.

The icons included in Bootstrap are the GLYPHICONS Halflings, of which there are 140. There are more available but at larger sizes and not available in any CSS Spirtes that I could see.

I resized the normal images to match the Halflings at 14px, altered the colour to match the #464646 Hex too and finally combined them into a handy CSS Sprite.

Enjoy.

The CSS code is:

    display:inline-block;
    width:14px;height:14px;
    *margin-right:.3em;

    vertical-align:text-top;
    background-image:url("glyphicon.png");
    background-repeat:no-repeat;
}
