In several places where I used to live, there were impressively useful large, well-organized libraries which I used all the time, both for research and personal browsing. The library closest to where I live now had, up until recently, one moderately-sized room of books, not divided by subject or genre but in two groups, fiction and nonfiction, all in alphabetical order by title only, and the card catalog was listed alphabetically by author. Recently a new building has been built with room for more books and more librarians hired (or people who work there anyway, I haven't examined any credentials), but the cataloging system is still catching up (it has been transferred to computer, which has its good and bad points), there's still only two subject sections (though they've now also divided hardcover from paperback), and it's still the only library in the area with more than a small compliment of books and librarians.
What you use often depends on the quality of what's available.
I'm a cynical optimist. I think the only way out is through, but once we get through it'll be better. Very different, but better. Howard Tayler
