Reddit mentions of Self-Rescue (How To Climb Series)

Both of these are good.

Escaping the belay from any type of belay is an essential skill to have. (Here's a famous example where the belayer had to escape the belay to rescue a fallen leader due to rock fall two pitches up.)

But as a leader you may have to escape the belay, fix ropes and rescue a follower. Of course it's easier to escape the belay when the belay is on the anchor but it's good to know what to do when you're belaying off your harness either from above or below. Here are a couple resources that may be helpful.

• Escape Top Belay (Belay from Anchor)
  
• Escape Top Belay (Belay from Harness)
  
• Escape Bottom Belay (Belay from Harness)
  
• Escape Bottom Belay (Belay from Harness) (More in-depth)

  Glad you can recognize this. Think of self-rescue as an integral part of being prepared to get on a multipitch route. Without having self-rescue skills you exponentially increase the risk of not being able to be rescued at all.
  
  Good luck and have fun!
  
  Edit: This book definitely helped me start to think about belays and rope management not as a series of steps to follow but as systems and how to adapt in all sorts of scenarios.

I'd suggest Fasulo's Self-Rescue, but the Tyson and Loomis book is also good.

Key things are regular practice and having the basic elements (knot passing, rigging a hauling system, load transfers, etc.) down cold. That way if something does go wrong you can focus on the plan to get the person down (or up) rather than trying to remember how to tie a load-releasable hitch.

I forgot to add, there are some great books out there that are super inspiring and useful.

For $9 there is no reason at all for anyone doing multipitch not to read this.

To be proficient at getting yourself out of trouble you have to practice it but at least having an idea of what you could do is better than having no clue at all.
