On a Mac, press Control + Command + 2 in Safari to pull up the Reading List sidebar. Right-click the one to delete, and then select Remove Item. In the same menu, you can select Clear All Items to delete the entire Reading List. On an iPhone tap the History icon in Safari (it's shaped like a book), and then choose the icon shaped like spectacles to open Reading List. On the iPad, select the menu in the top left and then select Reading List. Swipe left on a link to remove it, or choose Edit to pick multiple sites.
