In the initial stage, "digital library" will focus on collecting electronic dictionaries scattered on the Internet. Among them, the format of electronic dictionary includes Startdict and Mdict, and so on. The error in character input is unavoidable, thus uses can refer to the corresponding PDF dictionaries in usage. In this way, it can not only save users' time spent in network search, but the combination with this input method can also save the time cost of learning and improve the efficiency and interest of learning. The collecting and organizing work will continue.
