The Friends of Danbury Library has opened a used bookstore to raise money for the library's programming.  The nonprofit was forced to cancel its large annual book sale last year due to the pandemic, and will not be held this year because planning needed to start before coronavirus restrictions were eased.  The Friends of the Library has thousands of donated books in storage and most can be purchased for $3 or less.  The Friends Red House Book Store is located in the historic red McLean house at 15 Main Street and open Fridays and Saturdays from 10am to 3pm this month and next. The store can only hold four to five people at a time. Masks are optional.
