Most often it's attached with galvinized spirial 8 penny nails, not screws.
There is no book to tell you how to do that one.
Is this T-111 siding?
If it is your going to first have to measure to see if each panel is only 8' tall. A lot of older homes were done with 9' or 10' panels which are now in most cases special order.
Next comes the fact that if it is T-111 there's a few differant patterns avalible, smooth, rough, 4, 5, 6, 8" spacing between the cut in low spots.
The ends of the pieces over lap each other and thats the tricky part to get loose.
Your going to have to look over the panels to find where the laps are and only remove the whole panel not a section in the middle.
I use a cats paw pry bar to remove all the nails I can in the field leaving the ones near the over lap for later.
I make two cuts in the panel running up and down about 2" from the ends of the panels, remove the center section then use a flat bar to try and get behind the two parts still in place just enough to lift them a little but so I can get a sawsall with a metal cutting blade in the space to cut off the nails.
The reason you have to do it this way is because where the lap is on one side the nails holding it in place are covered up by the panel to the roght or left of it depending on how the panels were installed.
Most of the time these panels rot because they were installed to close to the ground. It's suggest in the install info to never have them closer then 12" of the grade and 4" from any shingles if there on a gable.
DO yourself a favor and start thinking along the lines of going over that wood with vinyl siding and save yourself alot of work every year patching, painting.
