The following list provides representative, but not exhaustive, examples of journals that can help you identify and locate data and data sets that have been made publicly available.
Most of these journals publish "data papers" that describe specific data sets - what data were collected, when, where, how, what software packages were used, where to access the data, etc. - rather than analyze the data. The papers link to the data set location. Some journals are dedicated to publishing only data papers and articles on topics related to data management and use. Others include data papers along with standard types of articles, such as research articles and reviews. A few are the traditional type of data journal that publishes only articles focused on presenting data in those articles.
