2)Non Normal situation Checklists
In the Normal situation Checks above, there are off nominal sections to deal with non critical procedures
For time critical procedures that must be performed within 5 minutes, there are the so called Pocket checklists ( Ascent, Orbit and Entry)
They are almost the same.
Ascent
The Ascent PCL contains procedures that safe systems for continued flight. It also contains orbiter systems powerdown procedures.
https://www.nasa.gov/centers/johnson/pdf/366508main_APCL_G_O_1.pdf
Orbit
At the initiation of the post insertion phase, the Orbit PCL is utilized. This PCL contains critical orbiter systems malfunction responses and powerdown procedures. The orbit PCL often refers to the orbiter Malfunction Procedures (MAL) Book for detailed troubleshooting.
https://www.nasa.gov/centers/johnson/pdf/359853main_OPCL_G_M_10.pdf
Contigency Deorbit in case of Severe malfunctions in Orbit ( Loss of cooling systems, or massive elec failure,..) that would lead to a fast deorbit.
https://www.nasa.gov/centers/johnson/pdf/359894main_C-DO_G_L_8_P%26I.pdf
Entry
The Entry PCL contains critical contingency systems malfunction responses that allow safe continuation of the pre-deorbit through early entry phases along with orbiter systems powerdown procedures.

IV)Space Shuttle Books
To Orbit and Back Again
Like a SCOM, less cryptic, full of anecdotes.

Into to the Black
Book about STS 1, it reads like a Thriller
https://www.thespacereview.com/article/2982/1
Shuttle Down
Book about an hypothetical scenario. What if the Shuttle was launched from vandenberg and would have diverted to Easter Island
