Consider a little better product.

Use the white pine as a "prototype" and learn
how to make a "basic" bookcase.

I would then use a oak or birch plywood and I would
assemble them with glue and pocket hole screws.

If you don't have a Kreg jig, this would be a
excellent reason to buy one.(for Christmas)

Don't have a table saw ??? Don't really need one...

Use a jig and a circular saw....

A simple bookcase can be done with very basic tools.

So i got my first router and after few plays with making garage shelfs i
want to make a real bookcase.
I was thinking of starting with pine, but am afraid that it may be to soft
to last as a nice bookcase.
Is douglas fir a reasonable compromise? or maybe i can make it with pine and
make surface harder by
finishing. Or shall i take it all in stride and make it from oak: oak
plywood with oak boards for walls and shelf edges. Any advice is welcome.
