can't redownload digital booklet

Thanks for your reply. It's not that I'm having trouble tracking it down; the booklet doesn't exist on my computer because I am unable to download it. As the first picture shows, when I try to redownload it in iTunes, it won't let me click where it says "purchased" - even though i unhid the album and was able to redownload all the other songs. As the second picture shows, there are no books/pdfs/digital booklets in my Books app. The issue is that iTunes won't let me download the digital booklet even though I have purchased it (years ago, granted, but I still think I should have access to it! At this point I'd be willing to pay to purchase it again, but it won't let me repurchase either!)
