Also, usual reminder that Sci-Hub exists and has all the research papers available for free from any journal.
Try libgen scientific articles, e.g. http://libgen.io/scimag/index.php?s=archaeology .. ALso you can search by journal number (or click on journal name) and all issues are shown in a table.
If you can't find it on Sci-Hub, chances are that a top-tier R1 does not have it either.
