More often than not finding rare books and zines is all about the hunt, but if someone can take all the hard work out of it and bring a great selection all to one space, that makes perfect sense to me. IDEA Book Store is a pop up bookstore at St Martins Lane Hotel in London. What’s even better is the wide array of titles and prices, ranging from £10 to £5,000. This can’t be missed. You’ve got just 3 months.
