Mistborn is an awesome series within the cosmere. the books to the side are several picked out from around the mistborn world and are some of the best. the abilities in the book are very creative and take a very different perspective on the supernatural. there are currently 7 books on the mistborn planet, 3 in the first series, 4 in the second, and there are 2 more 3 or 4 book series planned.

The stormlight archive is an amazing world so well developed and with things that would leave earth in ruins. Each book is around 12 hundred pages long and while only 5 books have been writen there are ten planned. the Stormlight arcive is a key player in Sandersons plan for the cosmere and is filled with amazing world development and plot

Evan Like Skyward. Cause of M-Bot. and everything else. but M-Bot

while many of Sanderson's books are in the cosmere there are still quite a few that aren't. all the ones to the side are but others suchas skyward or steelheart are just awesome books not in the cosmere.
