Does it have to be reclaimed wood? You can distress "new" wood yourself pretty easily. No it will never have the richness and tight grain of "old wood", but if what you're really looking for is the distressing, you can do it yourself. Or, take a look on Etsy if all you want is a couple shelves.

I had a local woodworker who specializes in salvaged wood custom make a door and window trim for me -- it wasn't cheap by any stretch of the imagination but his work is beautiful. So maybe ask around locally if anyone knows anyone -- I found my guy through a recommendation of a stone mason I used.

Agreed, try for a local woodworker, but if not--there are a number of sellers who offer these on Etsy. Two of ours are from Rejuvenation, but they don't seem to offer them currently. I will say that the salvaged wood shelf from Rejuvenation and the new wood shelf from our local lumber yard look very, very similar. (Rejuvenation didn't sell the size we needed for our deeper shelves so we had it cut locally.) Both are Douglas fir. We have two that are 8" deep and two that are 11" deep and find both sizes valuable--just depends on what you want to store there. (Our 8" shelves have cooking oils and vinegars in one area and coffee equipment in another; our 11" shelves have all sorts of things, but especially mugs, and are the right size to fit those three deep perfectly.)

out that far on the island may not be productive for your search. I would locate a source up in the Berkshires or that way. If you can find woodworkers groups you'll get directed ....or the Chamber of Commerce etc. . For shelves, the horizontal plane wont show off the nature of the wood...you want to see those boards on the vertical..like back of an island or something. Maybe have a Plan B depending on the project details.
