If it's been a while since you last opened a book, I think showing the last paragraph you read is better, gives you context. I've experimented a bit with indicating the current paragraph (for example making that paragraph black and the other paragraphs dark grey), but didn't find anything I was happy with. I think the mild annoyance of even the most subtle indication over hours of reading would be worse then the mild annoyance of picking the "wrong" paragraph, which you will only notice when you browse the library and open a book.
