Best Adhesive for Particle Board

I am building some in-wall bookcases with particle board. They will be installed between studs, and I will be nailing them to the studs. For the bookcase joints, I will be applying adhesive and then following up with 15g nails. I'm wondering what the strongest, and longest-lasting adhesive will be for the joints. Wood glue? General purpose construction adhesive? Liquid nails? Something else?

Once these bookcases are in, I will drywall around them, and they are not coming out for many years. Maybe decades. This will be in a semi-finished basement in Wisconsin. 4 seasons, with a wide range of dry to humid conditions. The basement is heated and air-conditioned.

Thanks in advance!

 

I use particle board for shelving in my garage and storage room. For shelving that needs to be pretty something like MDF or veneered plywood could look better.

I generally use a high quality wood glue. I keep Titebond III on hand so that tends to get used for a lot of wood projects. But, simply butting one board against another with glue and brads isn't the best joint. Stepping up in quality biscuits or dowels could be used in the joint. A dado or rabbited joint is another option. Basically a slot routed or cut into the vertical side boards to accept the horizontal shelves.

 

Gotta be honest, the glue is not going to be the weak link here even if you use cheap stuff. I would never use particle board for something like this.
