Thanks for visiting. You can certainly browse the links as they first come up but if you are looking for something in particular, here are a couple ways to pare them down to find what you are looking for. Use the buttons to choose one or more categories. Sites with tags for ALL of the buttons chosen will be displayed. Click "All" to clear all selected buttons or click a selected button to deselect it. Example: if you click "observations" you will get a fairly long list. If you then click "aviation" you are only going to get sites tagged both "observations" AND "aviation" and so make it more likely to find sites that have observations more oriented toward aviation. Use the search field to bring up list of sites with your search term in the site title or description. This will search only the sites already displayed based on the buttons chosen at the time, so clear the buttons if you want to search the entire collection of links. When you click on a link, the website should open in new tab on your browser. Titles starting with * are ones I've hand selected as perhaps the most helpful (my favorites, in essence). Unfortunately searching on * does not seem to work, but these sites will be shown at the top of any list. If you have suggestions for new sites, or you notice a dead link, please let me know using our contact form. Jim Green
