Books about ... Books

You know I love to read. Seriously. But I've discovered another thing I love about reading, and that's reading about book lovers. Because I always find something else to read while reading those.
What am I talking about?
Last week, I read a book called Authentically Izzy by Pepper Basham. It's by far my favorite read of the year so far. Izzy is a book lover, and she's constantly referring to and quoting books she loves.
Have you read anything like that? Well, here's the thing, in listening to her gush about her favorite books, I added to my TBR. ​A re-read of the Lord of the Rings series has been on my list for a while now, but I really want to after reading about Izzy's love for them. And I've been interested in picking up another Agatha Christie. 
She also mentioned Wodehouse, and I don't think I've read any of his. And I think she quoted the Count of Monte Cristo, which has been on my list of "need to reads" for a while. Maybe this year is the year to do it.
Another author who has introduced me to other books by her mentions of them in her own is Katherine Reay. She's a definite favorite of mine, right along with Basham. Reay's books are often about book lovers and because of her, I've read Daddy Long Legs, which I adored. She's also almost convinced me to read A Picture of Dorian Gray.
There's just something about reading about other people as they gush about books that makes you want to try them out for yourself. Or at least, that's the way I function.
What about you? Do you love reading about book lovers? Have you ever tried out another book because you read about it first?
