Like to add a little comment to Kent's and his referenced write-up.
Boiled Linseed oil is not a "Finish." And yes, over the years, folks have been lead to believe it is. In point of fact, "Oils" are not "Finishes." Extreme care must be used with "Tung Oil" as there are some Tung Oils that will NEVER dry and will smell for ever.
To accurately explain finishes, takes a Book. On which I have several. Ain't enough band width here. However, were I to make a recommendation, it would be a good water based varnish. Oil base varnish will result in a tiny bit of yellowing. I also prefer the soft appearance of Semi-Gloss. YMMV
