I ' m not talking about opinion , nor am I a Hillary supporter . I stated the GOP are socially conservative . They are . There is no argument to be had here . As I said you may as well try to argue the earth is flat . The GOP are open about being socially conservative as their voter base is largely made up of social conservatives . The opinion part of it is whether social conservatism is good or bad . The existence of it however , is not to be debated . <| sep |> Yes , once you have the books in Calibre , you can delete them from elsewhere . It took me a while to trust this , believe me . And I back up my Calibre libraries like a squirrel expecting a bad winterthree external drives , with varying backup frequency . Since many of my books are epubs I ' ve converted , proofed and corrected from something else , I can ' t even estimate the hours I have invested in those libraries . Normally I just download to the downloads folder , put them into Calibre , then off to the rubbish bin for the downloaded file . I ' ve got a couple of other holding areas for tricky cases , or when I don ' t have time to process something right away . Of course for a project like doing a book by OCR from page photographs , I ' d set up a separate project folder . I actually have several Calibre libraries fiction and nonfiction are the two main ones . Then I have one for a special interest group I belong to , with only a few dozen books , and a test library , where I can safely try out new stuff without risking the main collections . This help you out ?
