The bookcase is taken out of an issue of American Woodworker. The article showed how to make jigs for the tapered sliding dovetails which were still fairly difficult to get right. I definitely learned a few things about jig setup and sizing of the joints to accommodate glue! I had to adjust the dimensions slightly to fit where I wanted it to in the house and to work with the size lumber I had on hand. That lumber is spalted maple I got from my in laws who have some property and keep me supplied with free rough sawn lumber. I stained it with Minwax English Chestnut to mute the color variations a little and then finished it with wipe on poly.
