When I remember passages from books I definitely recall whether it was on the left or right leaf, top or bottom or center, and roughly how far through the book it was. If I read it on an e-reader I may have some recall of the vertical positioning but nothing else. I can take a book from a shelf that I only read once years ago and find a specific passage in a minute or two using this approach. For an ebook I have to try to remember a phrase and search for it, which doesn't always work if I remember just the physicality and sense of it, but not the specific phrasing.
