PRINCETON — The Princeton Public Library will offer a talk and reading by author Deb Borys from her book “Painted Black” at 6:30 p.m. today, Thursday. Also, the Friends of the Library will hold a preview night from 3 to 8 p.m. for Friends members for the book sale. The “Friends” have opened a permanent area in the library with their complete inventory of books for sale at the same low prices. The sale is starting a new phase by selling books in the library throughout the year instead of only at the April sale. The sale will continue from 10 a.m. to 5 p.m. Friday, and from 9 a.m. to noon Saturday.
