This chart shows 20 years of the Plainfield Library's tax rate. The bonds to building the current library were passed by voters in 1990, creating the sharp increase from 1989 to 1990. As you can see, the rate has declined steadily over time, 53% since the bond issue was passed in 1990. The tax rate requested in 2009 was consistent with the rate approved in the 1990 referendum.
Apologies for the size - Blogger won't let me make it bigger. But if you click on the image, it will open a new window with the chart only in a larger, more legible view.
