BackStage Library Works Newsletter: The BackStage Star

BackStage Library Works produces a bimonthly newsletter called the BackStage Star. Anyone can subscribe for free to the newsletter and then receive it in e-mail, with links to the complete stories on the web site. However, you cannot just access the newsletter from the web site. (To subscribe, see the link on the homepage in the upper left corner.)

The current issue of the newsletter contains a short article on "Newton Rings." As the newsletter says:

Newton rings are a type of interference pattern caused by light being reflected as it passes through multiple surfaces.

The article then goes on to explain briefly how to scan materials without getting these rings. Newton rings are often associated with digitizing transparencies, so if you're doing that, you'll be interested in this article.
