The design of the bookshelf is interesting and using lumber is a great way to save on costs. However, I would have appreciated more detail for a paid product. There was no recommendations on screws to use, how to do the doweling without splitting the wood when doing that on the ends of the boards, how heavy the final product would be, how to make sure everything is level and correct, how to deal with rocking if the bottom board is uneven or warped, etc. I guess the plans assume you are a journeyman woodworker and should know all this stuff ahead of time.
