RefDesk is a FREE site that has been around since 1995 that indexes and reviews quality, credible, and current web-based resources. RefDesk has a myriad of (link) information conveniently categorized on one page and is highly respected as a family-friendly web site that does not not link to sites that promote pornography, gambling, alcohol, tobacco or other ‘adult-related’ themes. You can pretty much use RefDesk as a launching point for just about anything you are looking for (i.e. news, searches, dictionaries, trivia, the list goes on and on…). Many people set RefDesk as their browser homepage. (Note: Your homepage is the page you initially see when you start your web browser.).
