In order to accurately find out the needs of users of geologic data and eliminate the information gap between data users and data managers, the National Geological Archives of China (NGAC) has conducted the data collection of user's accessing logs to the master station of the Digital Geological Library of NGAC. The automatic recording method is applied to register the user's location, their searching keywords, IP address and other related information for constructing the accessing log dataset. In order to make better use of these accessing data, a standardized processing method and quality control system are adopted. The dataset provides the accessing records to the Digital Geological Library of NGAC's master station from the year 2014 to 2017, which realistically reflects user's behaving habits while obtaining geological data. It also provides a sound basis for the further constructions of geological data service website, the development and utilization of geological data, and the geological data management and services.
