Benefits of pin shelving include not having to dado for the metal standards
and a neater overall appearance.

I have used the standard L-shaped pins on lots of projects, including
some bookshelves, and they work fine. You are dealing with a shear
situation and the pins will hold a lot of weight.

But -- a couple of thoughts:

1. Cut your shelves so they are pretty snug to the vertical face of
the pin "L". You don't want the pins loose in the holes.

2. With heavy loads such as books, your shelf can be the weaker link.
A three foot bookshelf can hold a lot of books, and paper is heavy in
quantity. Consider some kind of structural strength integrated into
the shelf (i.e. A wider, thicker front decorative trim that is glued
to the shelf rather than decorative banding.
