Would this book be considered a relic of S.D. John A. Hardon, S.J.?

According to the 1980 edition of *Modern Catholic Dictionary* by S.D. John A. Hardon, S.J., a *relic* is defined as follows: > An object connected with a saint, e.g., part of the body or clothing or something the person had used or touched. Authentic relics are venerated with the Church's warm approbation. They may not be bought or sold. Those of a martyr are placed in the altar stone at the consecration of an altar. Relics are of three classes: the first is part of the saint's body and is the type placed in the altar stone; the second is part of the clothing or anything used during the saint's life; and the third is any other object, such as a piece of cloth, that has been touched to a first-class relic. I purchased the aforementioned dictionary from a second-hand book seller by mail and it arrived yesterday. I marvelled at the very good condition that the book was in for its age, except for a signed note that was handwritten on the first blank page. When I later took a look at the note, I saw that it had been written and signed by "John A. Hardon, S.J." His cause for Sainthood has already been opened; and so, Fr. Hardon is officially recognized by that Catholic Church as a *Servant of God.* **Question**: Though S.D. John A. Hardon has not been declared a Saint yet by the Church, and though the book which contains his signed handwritten note was purchased by me (not expecting such a note), may this book still be considered to be a *relic* of his? If so, should I have it blessed by a Catholic priest?
