I recently launched the Boolean String Bank (www.booleanstringbank.com), a library for adding, searching and curating Boolean search strings. Sign up for free and help to build a resource that spreads Boolean literacy while harnessing insights and best practices from others in the search community. Feel free to share or offer feedback. Thanks!
