There was a longing in her to run to the library and look for answers but she knew she would find none. The existence of a book detailing everything one needed to know about making a Horcrux and suffering its effects was at zero, if Draco could be believed.

Even Harry and Dumbledore had had very limited information, and the Hogwarts library had proven itself obdurate in aiding her search for answers as well.
