Library management system in a laboratory scale cooperated with book seller sites

A laboratory in an engineering college possesses many books about technology and science. While members in the laboratory mainly use the books, outside students sometimes borrow them. Members must manage the collection by oneself. We propose a library management system for a laboratory scale. The system cooperates with some book seller sites. It reads an ISBN of a book by a barcode reader to acquire the information by Amazon Web service. It adopts an IC chip reader for user check with a student card. The system offers purchase helping functions. It gathers book requests of members and tells a teacher to buy by a cart method of API. It applies adequate lending rules according to access permission. We also consider learning support functions, especially for books about information engineering. A user who have read a book submits his comment for understanding. He may upload his program as sample of practice. The following users can access restrictively for the educational purpose. We developed a prototype of the system, which has some database and basic functions. We carried out an experiment of user operation for usability evaluation to get some ideas for improvement.
