I'm using today's post to congratulate The Private Library on its 500th post. I've said it before, and I'll say it again: The Private Library is an amazing resource! Readers of the FB&C blog will know the Private Librarian--L. D. Mitchell--as the writer who has so graciously posted here every Sunday since May. When we recently tallied our top 5 most popular blog posts in the past few months, 2 of them were his. Thank you -- and congratulations!
