Websites and social media accounts are evanescent things, prone to disappearing in an eyeblink, leaving no trace of their existence. Some are so obviously a product of their moment that it’s hard to imagine them having any longevity. Nonetheless, just as we can enjoy the beauty of the wild violets during their brief appearance on spring lawns, we can appreciate a Twitter account devoted to critiquing the credibility of bookcases. (You may be aware that, in this age of enforced video interaction, it has become a “thing” to sit in front of a bookshelf during your calls, to help lend an air of erudition and gravitas.) So allow me to introduce you to Bookcase Credibility. Enjoy it while it lasts.
