Google is great, but it won't help you find information on just those Web pages you've viewed. For that, you need a utility on your Mac, such as SmileOnMyMac's recently released browseback. Unlike other Web history utilities, browseback presents the pages you've visited as chronologically stacked decks of card-like thumbnails, making it easy to, well, browse back through your Web travels. You can also perform full-text searches to limit the view to just those pages that match, and once you've found the page in question, you can view it in PDF as it was when you visited it, go to it in your browser again, save it to PDF, print it, or send it to someone via email. browseback is both fun and useful (Macworld gave it a Best of Show Award at Macworld Expo San Francisco earlier this month), and it's well worth a try. It's a 2.6 MB download, and there's a universal binary version available for those folks with new Intel-based iMacs.
