time, just a couple of useful numbers from my over sized library.
tallest books come out at 340mm so allow at least 360. most of those will fit on 280 deep shelves, but some books are landscape, and then will need to be about 300 deep, so for the bigger books, i find in most cases 280-300 deep.
then i have a number of books which are 250 high and 180 deep.
some special paper backs i have are210 high by 160 deep.
other more mainstream paper backs would be about 200 highest,
and max 150 deep.
for a decent look i tend to aim for up to the height of 1200-1220
three shelves for the bigger books, with the upper shelves being up to the
ceiling, but set back.
so you would have the lower bit about 300 deep, with the top being
between 160 and 200 deep.
what about reading or display stations where some books are placed upon
slanted shelves like lecterns and displayed open, or they could be places where you could stand and look at books. so some kind of sliding
system might be useful and maybe even good looking.
another thought is of course if you have doors on the shelves, otherwise
the dust is a bummer, then if the top shelves are set back, people will
always put objects on them, so maybe leave a display space of about 300
between the wider and narrower shelves.
as has been said before inset strips, or i actually used my dd40 to set the holes for the brass inserts and shelf supports. after years of making solid
book cases with 2 internal shelve fixed, i found this latest effort much easier.
final thought, if like me you are using mdf for the shelves, then they do need covering with varnish or something to stop the moisture leaching out of the shelves into the books.
also don't for get to look out for a magazine space, although they tend to fit within the 300 high profile.
look forward to seeing some of it.
