Sorry, got a bit held up. You have to stop adding questions for a bit!
In terms of literary agents, agents are not like training-wheels. They are business managers. Big authors, including the self-pubs eventually, almost all have agents because they have lots of complicated contracts for a variety of different licenses and they need someone to help market, manage their business stuff, deal with contracts, collect monies, etc. In the U.S. market, if you want to do partner pub or you're going to be doing a lot of subsidiary rights license sales, a literary agent is pretty much needed as part of the process. However, there are territories where publishers receive government funding and contracts are heavily regulated/standardized, and the use of agents for direct book contracts may be less. In Australia, for instance, our friends tell us that there is a fairly standardized contract so they are more likely to use agents for international subsidiary rights sales.
A lot of authors starting out may not be using agents and may be going to medium and small presses that don't require agents for submissions. This can work out great but it can also work out bad because a lot of the small press contracts are awful and have missing language, like how long the publisher has to publish the work. So if you're going that route, go use resources from author groups about contract language. Even though sometimes the advice is a little over-idealized and you'll likely have to compromise, they offer good guidelines. The SFWA (Science fiction and fantasy writers of America) offers stuff, and there is the National Writers Union (also US,) the Author Guild, etc. Mike Sullivan has offered a lot of useful info on self-pub.
Remember that you are, in writing a work, including the short ones, creating an intellectual property (manuscript.) And it is the exploitation of products from that property (book, audio book, film, game, etc.) So contracts are all about either licensing rights to produce, market and distribute product (publishers, etc.,) or vendor contracts to distribute/sell product (Amazon, POD, etc.) So when you self-publish, you are simply exploiting your own rights to produce product from your property. But if you are exploiting the production rights, then you aren't offering first publication exclusive rights to a licensee. You're offering
reprint rights -- a subsidiary right licensed to exploit your property. So if you self-publish your book online and/or in print, and then market the same property to publishers for partnering, that's a reprint license, not a publishing license. It's the same as a small press offering reprint or reprint paperback sub-rights to a larger publisher (and splitting the money from the license with the author.) As a self-pub, you are a publisher, not just an author. The license has already been exploited in some way, so it's not a first launch.
So you can self-pub and market a work at the same time, but it's then a reprint. And there are different issues in a reprint license. The publisher will consider if the likely market for the book has already found the book and that's pretty much the audience, meaning a reprint won't sell much more, or is it likely that the publisher can expand the audience with wider distribution, etc., which they likely expect if the book is doing very well in self-pub. How many rights in the property they can license is also an issue in reprint deals -- do they get print and electronic and you stop publishing, or only one, can they do hardcover or only paperback in print, etc. So it's different factors and attractions and you have to figure out, as a publisher yourself, what sort of licensing deal you want to do/offer to publishers and offer an agent to market for you if you go that route.
Finding an agent hasn't particularly changed much except that now the submission process is cheaper and faster because of online electronic submissions (which some agents may only take for queries, but most have gone electronic altogether.) Authors do indeed gather agent names from the Acknowledgement pages of their favorite authors' books. There are also associations of agents like the Association of Author Representatives. Their members agree to follow basic business practices, so that member list isn't a bad place to start. If you are going to a convention for other reasons (since they are expensive,) and they have agent/editor appointments, you can try that. Likewise writers conferences do usually have agents who are giving talks do appointments. On both of those, it's important to follow the rules. And it's entirely possible if you publish short fiction in various places or you are selling well in self-pub that an agent might come to you, but it's rarer.
Agents are dealing with thousands of authors who would like to work with them, which is not possible for them to do. So even the newer, more hungry ones are not that hungry that they'll snap up any author with an offer from a publisher. If an author goes and gets an offer from a publisher, then goes for an agent, the agent will be coming in late. The agent will have a lot less leverage to negotiate deal terms and may not be able to improve the offer much, as opposed to the agent being the one who submitted the work. And there can be contractual issues of whether the agent is going to be the agent of record on a deal you first got yourself. If the house is smaller, there may be not a lot of money on the table and it's tricky to be able to take the work to a larger group of publishers from an offer made by a publisher in good faith on exclusive submission. There is a time constraint. So it's not automatic if you get an offer. An agent will usually want to take a look at your book property before deciding because it's a long business relationship, even with the time constraint. But it does sometimes happen. If you somehow got an offer from a big publisher without having an agent, certainly you would want to go and try to get an agent. If you can afford it and you get an offer from a publisher without an agent, you could hire a lawyer versed in literary law to look over your contract. The lawyers tend to push for things that aren't going to happen, but at least you'll know about any hidden pitfalls.
Because there are thousands of authors submitting to both publishers and agents, they don't like to have spent time reading something and working up an offer for rep or license and then finding out it's with fifteen others and they wasted their time. So the publishers want an exclusive submission from authors, if they are unagented, and put up with multiple submissions from agents because they have to because the agents have multiple authors. And the agents do not want to get in compete wars with other agents over authors.
The reality is that authors often skirt around these exclusivity commitments and I'm not going to tell an author not to do that. But one way you can manage it is by sticking in a business-like manner to the response periods the publishers and particularly agents tell you they aim for, and you can give them an exclusive for most of that time period. So if an agent's response period is two months on a partial ms. submission after query or a query packet, then when you're getting to the end of the two months and haven't heard, you can contact them about whether your stuff is still really being considered. If it is, you can then still leave it there if you want, or withdraw it, but the exclusive look is done and you can send it to the next agent. But that second agent is then not getting an exclusive and you may have a problem if both first and second agents want to rep you. It's a balancing act and it's still slow. Electronic submissions are faster processed, which helps.
Another question is about blogs and websites. I'm dabbling with putting one together and am looking at Wix, Weebly, Wordpress, and Blogger. Is there a "go-to" platform for SFF authors? I'd like a platform that I can both blog as well as put up sample chapters and other "freebies," that is fairly easy to use and versatile, but has a lot of nice theme options. I know: I want it all.
There is SFF.net, which a fair number of SFF authors use. Wordpress is used by a lot of folk. If you're doing the basic free stuff, then there may be limitations on how you can set up sites, but I know that John Scalzi, for instance, is very happy with a pay package with Wordpress. Blogger is an old one mostly for blogs, but some may use it for sites. Wix is new and seems to be pretty aggressively advertising, and I have not heard of Weebly before, so they may be new. A lot of authors used to use LiveJournal for blogs and some still keep those, but mainly it's not very popular anymore. A lot of authors use Facebook and Twitter, and some do Tumblr as well. You don't have to do any of them. However, if you are working with a publisher, they're going to want you to do a website at this point.
Going back one post, my general response is a sense of just how much luck is involved in whether or not your book sells. I mean, if it is a good book, chances are you'll at least find a small readership. But for a book to be a hit, it seems that quality is less important than whether or not the book hits a particular cultural nerve or literary fad, and whether you happen to follow the "right" combination of steps to get your book to wider attention (which, in turn, involves no set formula). Maybe it isn't entirely luck, but it certainly seems to involve a good amount of it. Hard and quality work will get you published (eventually, some way or another) and read, but it won't necessarily lead to popularity or broader success.
Luck is very much a part of what may happen in the fiction market, but not in the way that you are thinking of it. Luck is partly involved in finding a partner publisher to believe in and invest, in making people aware of a book's existence and in word of mouth happening obviously. But it's not luck of marketing and pretty packaging (although a nice cover doesn't hurt in SFF.) Again, fiction readers are promotion resistant. They don't give a crap about cultural nerves or literary fads. In SFF, they've been reading about the same monsters, myths and spaceship adventures for centuries. Murder mysteries have remained murder mysteries. You don't get any social status for reading a particular book like you do for owning an iPhone or a designer purse or the latest hot game or being the first to see a movie even. Nobody cares what novels celebrities are reading. It's not like other entertainment sectors. Readers like what they like and they all like different things. The market is broad and it could be a lot broader and that's how it grows. The fiction market is quite small compared to other products but it's loved. There are people who love Twilight and there are people who love The Kite Runner and there are people who love The Melting Dead, and sometimes they overlap and sometimes they do not.
There is no such thing as "quality" and "merit" because it is all subjective as to what is good and what is not, and no one thing runs the market. (And claiming you're more hard-working than other authors will not leave you with a lot of friends.) What mainly happens with a book being a hit is that a lot of people, one way or another, find the book and like the characters in one way or another and find meaning and entertainment in the narrative one way or another. And they talk about it to their friends. This is insufficiently sexy enough a rationale for a book doing well for most people, but it is very much what happens. You should certainly be aware of what is out there in the market and coming out, because fiction is a symbiotic market and knowing lets you be able to describe your work effectively with quick references. And you can try to write to trends if you want; some authors do. But publishers are buying licenses three to one years ahead of bringing the books out, and self-publishers put out fast and in mass quantities so it's every which trend.
Publishing folk will try to "guess" what might happen and what might be of interest, and authors keep an eye out for opportunities and drift from one sub-category to the next in the field they like, which means we often get clusters of authors who happen to end up doing similar stuff. But every sector of the market has to keep churning, and publishers -- and self-publishers for that matter -- are bad guessers.
Take vampire books. We always have a steady stream of vampire books -- hundreds, thousands of vampire books for decades and decades -- romances, horror, contemporary fantasy, historical fantasy, alien SF vampires, etc. Some of them sell and some of them don't. And even more thousands of vampire manuscripts get rejected by publishers as not right for them. But when a small group of authors doing vampire fiction do well and/or we get a phenom seller involving vampires, several things happen. First, because fiction is symbiotic, the publishers do extra marketing of their vampire titles to try and attract attention of readers of the hits. They also do it with other fantasy fiction, including epic sec world fantasy and science fiction that has nothing to do with vampires because an interest of more readers in fantasy fiction means some readers will drift browse outwards, but definitely some of their vampire titles. And the media does not like lone hits. They like to make articles about trends. So they make trends by bundling hits together. And this increased media attention helps attract readers to fiction, but it ignores most of the market and other hits.
So in 2003, 2004, you'd go ask agents and editors and pundits on panels what's selling in SFF, they'd say, well write a vampire novel, that's all that's selling. Except that wasn't true because reams and reams of vampire books were not selling to publishers and on shelves, in fantasy or fantasy romance. And publishers were buying other books than vampire books and putting them out and some of them were hits. Lots of dynamic things were happening in sec world fantasy and many sectors were expanding. But the media liked vampires and then they liked zombies, etc. Meanwhile during that period, SF was pronounced to be dying, again. Fantasy was all the publishers wanted, it was growing so big and SF wasn't, the readers were dying off in age, it would be abandoned, etc. But if you looked at the whole market, that wasn't true. Four years later, SF was rapidly expanding especially in the young adult demographic, and now it's a little star in the fiction market (and in other media,) and The Expanse is a t.v. show. So if you predicted the trend that SF was in eclipse in 2004, you were wrong. If you predicted that vampires would dominate everything, you were wrong, and if you predicted that vampire books would basically disappear out of favor, you were wrong because the vampires never die.
So no, a special snowflake of a quality novel will not only be a niche novel that can't be a hit because it doesn't hit some sort of cultural nerve. It may be a hit, it may not be. Most authors take a span to build up enough of a fan base to get to bigger numbers. Most of the authors who are sudden hits are utterly surprised by that happening. (A few believe that they did it with massive advertising, but they are wrong.) And luck is involved. Your publisher partner avoiding bankruptcy may be involved. Amazon soaking you for algorithm fees may be involved. Your spouse having a health crisis so you can't promote may be involved (though we hope not.) But it's not the luck of being a shallow trend-spotter, because look at all those different best-selling authors from National Book Award winners to erotica. Which trend is the magic key then? And why doesn't it work with every single book each of those authors puts out? (Because it does not.)
But that's not a bad thing. It's an opportunity thing. It means there's a wide pool that can be jumped into by anybody, that you are not sunk if you don't have the magic marketing formula or a lot of money. It means you can find an audience and build a career, big or small, and word of mouth can have phenomenal effects.
So I generally tell people to look at the market not to try to game it, because you'll fail and pull out your hair, but to see where what you are writing fits in it. Because you do fit in it somewhere. And you might sell in it too. And if you're not a white male in the West/English language market, or a male elsewhere, there are some things you will probably have to deal with/be aware of unfortunately, but there is still opportunity there. More than you'll get in any other area of entertainment.
I think I got all the questions, but let me know.
