Bibliomania is a compulsive tendency to collect and hoard books, according to Right Diagnosis. Although bibliomania is not classified as a psychological disorder, it can be a form of obsessive-compulsive disorder, notes Dr. Mark Griffith in Psychology Today.
Bibliomania is collecting large volumes of books, which are nonessential and usually not even read. Patients who have this condition can often collect many copies of the same book and even steal books. By collecting and hoarding books, a bibliomaniac may feel a sense of relief or a reduction in anxiety.
Dr. John Ferriar is credited with first using the term bibliomania in 1868 to describe this condition, according to Dr. Griffith. People affected with bibliomania can experience health problems and seriously impacted social relationships.
