One thing I would add to this article is that the Biodiversity Heritage Library has scans of many older general scientific journals (not just those related to biology/life sciences), which are invaluable to anyone working in the history of science. I have used it frequently in my work on the history of mathematics.
Many of the same journals are available elsewhere, e.g. archive.org. But finding particular journal volumes on archive.org can be hit-or-miss, depending on how complete+correct the metadata is. The BHL lists the volumes for each journal.
