If you are a friend of libraries then I think you probably like words. If I am correct then you have to visit the website Dictionary of Obscure Sorrows. It provides new words with accompanying definitions.
vellichor, n. the strange wistfulness of used bookstores, which are somehow infused with the passage of time undefined filled with thousands of old books you’ll never have time to read, each of which is itself locked in its own era, bound and dated and papered over like an old room the author abandoned years ago, a hidden annex littered with thoughts left just as they were on the day they were captured.
moledro, n. a feeling of resonant connection with an author or artist you’ll never meet, who may have lived centuries ago and thousands of miles away but can still get inside your head and leave behind morsels of their experience, like the little piles of stones left by hikers that mark a hidden path through unfamiliar territory.
Vellichor reminded me of the following picture of a used book bookstore I took this fall in Sienna, Italy.
