Abstract College used book trade is different from the general online shopping. Recommendation engine applied common recommendation algorithm cannot be very good to recommend. In order to make students’ used book shopping site better to recommend books to users, to improve the accuracy of the results and the efficiency of recommendation, based on the original recommendation module, the paper proposed a suitable mode for shopping website of used books recommendation engine with an optimal recommendation algorithm module. The new algorithm module has the following characteristics: (1) Based on the items of the recommendation algorithm, books’ scores and "old and new" factors are taken into consideration to optimize recommendation results; (2) For the convenience of users purchase, a new packaged recommendation function is added, so users can buy the required books by pushing one key; (3) According to the fact that the needs of students can be predicted, the recommendation algorithm was designed based on time nodes.
