M3 collects data on articles published by FOCUS online. Due to copyright regulations, we do not collect entire articles but only meta information on them. We also store computational representations of the article in several derivations. As a researcher and for non-commercial purposes, you are free to use these materials through our API. We imagine you using these materials either as-is or as a sampling starting point to rehydrate the full articles for your own research project. Note that collecting full articles for a specific research question (rather than an archive) is usually covered by legal regulations and does not depict a copyright infringement (also note that this does not include the open sharing of full-text articles as-is; you should, however, consider sharing document-feature matrices with your publications). In order to make things as easy as possible for you, our API includes an endpoint for rehydration so that you can quickly iterate over the results of this endpoint to scrape the articles necessary for your own project. Use your own or the scrapers provided by M3 in our GitLab . In case you make use of M3 for your publication, please consider citing our project.
