As I collect more documents in my iBooks on my iPad, it would help to have a cover page or title page that shows up on the "shelf." Otherwise, I can't tell which document it is until I open it.
In the top right corner of iBooks, next to the button that says "edit," there is an icon that looks like a list -- dots followed by lines. Tap that, and you switch to list view, which shows the titles of the books.
When I do that, it shows the list and the names. But on the bookshelf, the name still does not show up. Yet somehow, my other two PDF files there show with a colored book jacket and the title on that. I don't know how I got those listed right before but somehow can't get the book jacket look on this PDF file.
