classification at home

calimacIn a f'locked post, a correspondent queried readers as to their preference in classifications for a home library: Dewey Decimal, Library of Congress, Universal Decimal, or something else? Part of my response:
First off, for something the size of a home library, even a big one, there is in practice no difference between DDC and UDC. So don't worry about that.
LCC's easier introduction of new subjects really just means that there's a more flexible notation space. So unless you plan to put spine labels on your books, that's nothing to worry about either. Both systems cover the full range of knowledge, and the practical questions are:
1) The ease of finding and applying the numbers; 2) The order of the books on the shelves.
Re 1): These days many commercially published books have cataloging info on the verso of the title page, including LC's assignment of both LCC and DDC numbers. And for those that don't, you can easily find them in LC's catalog. Advantage LC: LC hasn't always applied DDC, so older books won't have this. Advantage either: But you can look them up in other libraries' online catalogs too. Advantage DDC: It's shorter and less technical (outside of the literature fields, which are a bear), and can be and has been abridged (which LCC cannot, the flip side of the more flexible notation space), so it's much easier to use if you want to apply the numbers yourself.
Re 2): The big question here is, what are you going to do with fiction? Neither system is very comfortable with it, and neither makes any provision for separating genres. In practice, most LCC libraries integrate the fiction (and poetry & drama) with non-fiction about literature, while most DDC libraries put fiction outside the classification altogether. But this is because LCC is used mostly by universities, where the people who want fiction are literature students, while DDC is used mostly in public libraries, where the people who want fiction are readers who want novels for pleasure.
If you integrate the fiction, the ordering is quite different. Both separate it first by nationality of the author and/or language written (using different orders). But after that they're different. LCC classes literature of a given country by time period, making no provision for difference between fiction and other forms of literature. DDC classes literature of a given country by form - poetry, drama, fiction, then essays & letters and whatnot - and provision for further subdivision by period is optional.
If you want your nonfiction to line up on your shelves with a logical succession of subjects pleasing to the eye, both systems are wonky, though LCC is slightly less so. For my own shelves, I use this one, which is more logical than either. I use the old system, not the revised one, which is faceted to within an inch of its life (and, so far as I last checked, still incomplete); it's 60 years old, to be true, but it's not difficult to find places for newer subjects in my library of 3000 non-fiction books.
Most people don't have a broad selection of non-fiction in their home libraries; they concentrate on subjects of particular interest to them. For them, I advise not worrying about classification at all: lump the books up by categories. Now, for sub-arrangement within these, advice from DDC or LCC may be useful, but probably not as useful for your personal preferences as you might think.
It can often be better to take all your books on, say, astronomy, and sort them by piles on the floor according to how they go together in your mind. Most likely the star-gazing books will be here, and the astrophysics books over there, and so on. It's really rather easier and more intuitive than trying to eke the same info out of a classification system.

The term for what you want to do with Inklings books and Hitchcock movies is "special collection". I do that too. My post on my bookshelf ordering should be forthcoming at some point.
