COSine has long been known for its great discussion panels on a wide variety of fiction, science, and literary panels. We will have two tracks of main programming running from late afternoon on Friday through early afternoon on Sunday, plus author readings, special events, author's reception, and book signing.

We welcome anyone who would like to be on a panel or other programming item. If you would like to participate or if you have suggestions for program items please contact Mary Morman

You must have a membership to attend any COSine functions.

1pm — What Does “Published” Mean in Today’s Market? (Rampart)
The past two decades have seen an enormous turnaround in the way people read, and this has naturally led to different opinions on how we define a "published" work. Ebooks, audio, and podcasts are growing markets that often cut out the function of the big publishing houses, and in turn those publishers are doing less and less for their author clients. Where is publishing headed, and who counts as a published author in the middle of this cultural change? — Panelists: Sue Duff, Travis Heermann, Nathan Lowell, Astral Scribe, Carrie Vaughn, Peter Wacks(M)
1pm — High Fantasy and the Modern Reader (Breckenridge)
Some sixty-ish years ago Houghton Mifflin published a magical quest novel aimed at an adult audience. Tolkien’s work was so new and different in the 1950’s that there was nothing at all to compare it to. Today’s reader may find the themes of high fantasy so different and overused that they need to constantly push the envelope of magic to differentiate their novels from the mass of others. How did we come so far in such a short time? Is there still a market for fantasy? Have quest novels gone out of style? — Panelists: Scott Beckman, Lou J Berger(M), Carol Hightshoe, David Kilman, Thea Hutcheson

2pm — You Don’t Have to be Dead: Accumulating and dispersing books and other collections (Rampart)
Fans are collectors. They collect everything from first edition books to esoteric mimeo-printed fanzines (and comics and costumes and photographs…). If you want to keep control of how your collection is handled in the future, then you need to make arrangements while you are still alive to distribute and fund the collection you want to pass on. — Panelists: Kent Bloom(M), Kevin Ikenberry, Christopher Salas, Joe Sokola, Corie Weaver, Jo Walton
2pm — This Year’s Best: What are you reading and what do you want to nominate? (Breckenridge)
The brave and adventurous readers who agreed to talk about this year’s books will discuss what they are reading, why and how they choose what to read, and what they think might be nominated for the various 2017 SF literary awards. — Panelists: Andy Burns, Sarah Hoyt, L.F. Patten, Eric Schwartz(M)
2pm — Art Pickup (Art Show)
Pick up and pay for any art you bid on during the show or auction.
