Just browsing: How we decide what to read next

Does this happen to you? Need a book to read - finished Visit from the Goon Squad, liked it, but as I often do I move back and forth between classics and contemporary fiction, so poked around among my own library, hm, anything appealing?, not really, obviously have read at least once most of what I want to read or ever will read, Middlemarch has been beckoning for a re-read but it's so long and my pb edition is so beat up and small type - drifted through our nice but very small neighborhood bookstore, which, sad to say, is becoming more of a gift shop every day - at least it's surviving - looked across new fiction, nothing I'd want to read - then into the fiction aisles. Remembering the Proust volume I finished a few weeks ago and thinking of looking for the second volume, Among Young Girls, but, no, they don't even have Swann's Way - remembering looking at the list of Penguin Classics at the back - Master and Margarita? - I've never read it! - but they don't have that either. Bought a gift and left. Today - to the library! Yes, I have on one of my apps a list of books I hope to read, will check it before I go or at the library - will look first at new fiction, just because - but they never seem to have what I want - either too obscure and they don't order it or too popular (I should put books on reserve - but then they seem to come while I'm in the middle of War and Peace) - so will go to the back shelves - who ever browses there? - and see what I find, maybe Master and Margarita after all? Or else: back the New Yorker summer fiction issue, at least for a day or so.
