As a tip: paper authors are usually happy (delighted!) to send you a copy of the paper if you ask. If the citation is somewhat recent you'll at least get a good, crisp pdf, not a third generation photocopy.
But yes, papers are all created for print, not the web. Online repos (biomedcentral, arxiv, journal web sites) often do have a separate list of citations, and sometimes (as for biomedcentral ) links directly to the paper.
