We hope your're keeping cool while you enjoy this month's Sudoku puzzle!  In addition to puzzles, MHL offers a variety of resources, including an e-book on how to use the programming language C to create and solve Sudoku puzzles. That book, along with many other how-to tech titles, is accessed through O'Reilly for Public Libraries (formerly called Safari Books).  If you love e-books but tech guides aren't your jam, be sure to check out our e-book offerings via Overdrive/Libby and Hoopla.
