Our Novi Library book store is also getting fewer quality used books.  We believe that electronic readers have had an impact.  Even our older customer's are using them.  We still have many who like to hold a book.  They buy books and return them for us to sell again.  We don't have a big sale but have seasonal sales in our used book store.  Donations can be dropped off anytime and large donations are accepted by our facilities staff.  Road construction did have an impact a couple years ago.
