The main academic full-text databases are open archives or link-resolution services, although others operate under different models such as mirroring or hybrid publishers.

They filled the test tubes, analyzed the data, or designed the particle accelerator, or at least supervised those who did. Many, but not all, journal articles are primary sources—particularly original research articles.
