Because of a computer error, a Web address was incorrect in an article yesterday in the Howard County edition of The Sun about author Robyn Rhudy and her book on backyard pond gardeners. The correct address is http://userpages.umbc.edu/ ~rrhudy1/pond.htm.

Another article in yesterday's Howard edition of The Sun misstated the number of times Arthur Neal Willoughby has run for school board. He ran in 1996, 1998, 2000 and has filed again this year.

The Sun regrets the errors.
