<P>PROBLEM TO BE SOLVED: To provide a secondhand book circulation support system that promotes the stocking of good books by urging students to positively put up books (particularly college textbooks or the like) for sale. <P>SOLUTION: A management server 14 analyzes each student's learning directivity based on each textbook's auction history and trading history to create statistical information while going between selling students and buying students to provide the trade-related information of each textbook 30. A company delivers useful information (e.g, job information) to the students with specific learning directivity or individual attributes while referring to this statistical information. The students can acquire useful information matching their own learning directivity, by simply selling and buying used textbooks normally. This mechanism urges the students to put up books for sale to promote the stocking of good books. <P>COPYRIGHT: (C)2004,JPO |
