This morning I read an article about this on page 15 of the May/June 2020 issue of "This Old House" magazine. They suggested sanding with 150 grit sandpaper and then use a shop vac with a soft bristle brush to remove the dust. For the next step they suggested an oil base primer to assure good wood penetration. Then they lightly sanded with 220 grit sandpaper followed by the shop vac. You can then apply 2 coats of oil base or water base paint with a brush, roller or spray gun. They suggested lightly sanding between coats with 220 grit sandpaper. Personally, I like oil based enamel paint if you really want a long lasting durable finish.
A prior poster mentioned stain and varnish. Stain followed by 3 coats of urethane varnish will look nice. You can easily use a putty stick to fill nail holes and small problem areas. Before applying the stain it will be best to do a really good sanding with 220 grit sandpaper then wiping with mineral spirits or paint thinner to remove the dust. You will also need to lightly sand with 220 or 320 grit sandpaper between coats of varnish. If you paint the book case you can fill and then sand knots, nail holes, big gaps in joints and other big or small problem areas with spacklin.
