Why, yes, “The Year in Reviewment” would normally suggest a December date of publication. But the hurricanes down South sucked the lumber away from the Woodland Mills, so the last of the shelves didn’t arrive until early February. And then, well… Yeah. (N.b.: This is currently the first stage of book-shelving, wherein each book gets cataloged, measured, mylared and/or DDC categorized as appropriate, and placed on a shelf in some reasonable semblance of order. Then comes building the long-term shelves.)
A quick tour of the library so far! First up, and first to be built, there are the under-eave shelves in the study. Yeah, the boards are cut for that fourth case, they just need to be, you know… attached to each other. And stained. (See, this, this right here, is why I relented and used pre-made shelves downstairs. Because I kinda wanted all of my books off of the floor within a decade of moving in, no joke.)

Sized for standard hardcovers, made modular by the plinth underneath so they aren’t custom-cut for the baseboard (said modularity immediately nullified by angling the tops of the uprights to match the eaves), these have nonfiction, mostly biography and World War II history. 280 books shelved!
… out of 6,012, so ~4.66%.
