Not a fan of the Dewey Decimal System. The Library of Congress system is much better.
As a retired Librarian, I cannot disagree with you more than I do now. While you are welcome to your own opinion, and, everyone has things that work for them, the LC catalog makes very little to absolutely no sense to most library users.
With the Dewey system, I could get a subject just by knowing the first 3 digits.
The times I did LC, I found things....scrambled to say the least.
BUT, you must use what is comfortable for you.
