So very many mixed feelings.
On one hand, I have more memories related to Borders than any other store in existence. I've spent countless hours sitting on the floor with a pile of books, trying to decide which to get. Back in the '90s when Paganism first started to go more public, 'zines could only get you so far and mall bookstores didn't carry Pagan books (and the nearest proper Pagan store was a long ass drive), and then someone introduced me to Borders. OMG, I felt like I was in heaven. I've spent well over a thousand dollars in that place.
Yeah, I've got a Kindle now, and yes, I can preview a chapter. But it still doesn't beat being able to pick up the book and flip through it long enough to decide if it's something you really want to buy or not. And Borders-- a couple of them especially, until they closed-- were pretty damn good to the Pagan/occult community, you could find books that you'd even have trouble finding at the actual Pagan store if the section manager knew his or her stuff (the one of the managers at the first DC store was a Thelemite, and man knew his books!).
They've made some astonishingly boneheaded moves over the years, and the one or two times I've poked my head into one recently found them to be much diminished, a pale ghost of their former selves. But I'll drink a toast to Borders, for all the vistas their books have opened for me over the years.
