Family bible, half leather, the spine turns to rust-coloured powder on my fingers and there's already a 4cm loss at the head. Boards are still firmly attached. Everything I find about consolidants is either a conservation supply sold in litres or a forum post from 2007. What's realistically doable at a kitchen table without making it worse for a proper conservator later?
Warning from doing this badly once: don't spray it and don't flood it. One thin brushed pass, dry fully, then judge. I went heavy the first time and got a shiny plasticky surface that looks wrong and is now the thing a conservator would have to deal with.
Noted. Thin passes, patience.
Worth knowing why it happens so you don't repeat it with your other books. Red rot is acid deterioration in vegetable-tanned leather after a century of sulphur in the air, and it isn't contagious, but the conditions that cause it are shared. Getting the shelf away from a radiator and out of direct sun matters more than anything you brush on.
If you do reback, photograph the spine first, including the lettering, from straight on. If the original spine piece is salvageable at all it gets laid back down on the new leather afterwards and you'll want the reference.
Nitrile gloves and work over paper. The dust gets everywhere and it stains light fabric permanently.

They aren't alternatives. You consolidate first either way, because nothing adheres to powder.
Klucel-G (hydroxypropyl cellulose) in isopropanol at about 2% is the standard, it's sold in small jars by most bookbinding suppliers, and it's reversible, which is exactly the property that matters for not ruining someone's future options. Brush it on sparingly with a soft flat brush, let it dry fully, repeat if the surface still dusts. Expect slight darkening and don't chase that.
After that, rebacking is a separate judgement about handling. If the book lives on a shelf, consolidate, make a clamshell box, and stop. If it gets read, a Japanese tissue reback under the lifted leather is the least invasive thing that actually works.

Ordered the Klucel. The box-and-stop option hadn't occurred to me and it's probably right, it gets opened about twice a year.

Boxing is genuinely the professional answer for a lot of family volumes. Half the damage on books like this comes from being stored spine-up leaning against something.
