Whether you have your jerkin in a twist over movable type or are hyperventilating into a paper bag at the prospect of dealing with e-rights, have no fear: technology is, despite the insistence of some in the book world, your friend, and the better you know how to make use of it, the easier it will be for you to sell your books. Things are ever changing, mes auteurs, but the written word isn't going anywhere anytime soon.
First: if you don't know how to use a computer, now's the time to learn. Incidentally, I have no idea how you're reading this blog if you don't know how to use a computer, but I imagine someone might have made a daguerrotype for you and sent it by horseback, or maybe they printed it out and made mimeographs, or perhaps they're just reading it to you from the next room. Regardless, computers: learn how to use them.
Second: if you don't have a website, seriously think about getting one. Where else are you going to provide links to your book(s), aggregate your Facebook/Twitter/Blogger output, brag about your accomplishments, announce future events/readings, &c &c?
Third: writing requires research. Where does one conduct research? If you said "the library stacks," I have some news for you: ironic flannel is in, Grey Flannel is out, and anything acid-washed is super out. The Internet is the single most powerful and complete repository of human knowledge, useful and non-, ever invented, and the scholars at the legendary Library of Alexandria would have given their frontal lobes to browse through it for thirty seconds. Use it! (Both the Internet and your frontal lobes, that is.)
Finally: while I don't recommend it, if you absolutely insist on going your own way and self-publishing, there's a veritable panoply of options available to you now. You can print on demand! You can sell an e-book through Amazon! Your options are not limited to Usenet ASCII rants or .pdfs you made and linked to on your LiveJournal. You (perhaps with help) can create really great-looking POD books and/or e-books these days for very little money; if you're going to go solo, at least do it right.
I'm not saying any of you are Luddites or technologically illiterate, meine Autoren, but it's easy to be swayed against the rapid electronic evolution of the industry by a (very vocal) minority of myopic, stodgy publishing folk who are going into the twenty-first century kicking and screaming. Keep your eyes, ears, and minds open, seize any opportunities you find, and always look for newer and better ways to sell yourself and your writing.
