While it sounds like a plausible word for someone who studies books, it's not a recognized term.
Here are some terms you could use instead:
* Bibliophile: A lover of books.
* Bibliographer: Someone who compiles and studies lists of books.
* Librarian: A person who works in a library and helps people find books.
* Book historian: Someone who studies the history of books.
* Book critic: Someone who writes reviews of books.
It's fun to invent words, but remember to use established terminology when communicating professionally.
