You can use apple or fin ply which can be a decorative modern looking edge
just sanded and finished.
Solid wood is an option, using either birch or maple to match or walnut to
contrast.
The most common option is iron on edge tape. It comes in every flavor and is
real wood. The only hassle is you have plain square edges. The edges are
also fragile in case you have kids, have a big dog or get drunk and throw
stuff.

I shall shortly be lining out a redundant window alcove to form a set of
bookshelves. The dimensions are 80 inches tall; 24 inches wide and 10
inches deep. I am minded to use 3/4 inch birch ply. What does the team
suggest is the best way to hide the end grain on the front edges of the
carcase and shelves?

Many thanks.
