A vector version of this image is also available, and should be used in place of this raster image whenever possible.
Note: this file will not be deleted for this reason, unless it is explicitly nominated for deletion. Deleting this image might break the “attribution path” for the new SVG image, which breaks licenses such as the GFDL.

This was made by manipulating a scan of a Pickett pocket slide rule, done by me, Benjamin Crowell, in 2005. The slide rule does not have a copyright notice on it, and works published in the U.S. without a copyright notice before 1977 are in the public domain. I therefore think the slide rule itself is in the public domain under U.S. law. I'm making this diagram available under GFDL license.
