What is an issue when it comes to comics?

An issue is like an episode of your favorite TV show but instead of getting your fix weekly, an issue is sent every month. Issues tend to be small, almost always limited to 20 pages unless stated otherwise. If you want to be kept in the loop of what happens in your favorite comic series, this is the place to start. Also interesting to keep in mind: issues have a nice collector's value! If you have a bit more patience, I'd suggest to wait for a collection in TP or HC.
