ok, here's something else-
all of my cds are organized alphabetically by artist. no problem you say. if i have more than 1 cd by an artist, they are then organized by full length cd (including official live albums), singles, others (which includes bootlegs). . .within each grouping, they are organized by year released. so, if you were looking at REM, you'd see all the full length albums together, organized by year they were released, then singles (again organized by year released), then other stuff in some order that i determine.
my books are not so organized, unfortunately, mainly because books come in different sizes, and i probably couldn't stand seeing all that randomness in book size, even if i did organize them alphabetically. instead, i've had to organize by subject, then, if need be, by sub-topic, then by book size- i know, it makes no sense.
