I am curious if there is a way to use only a URL to send someone to a specific line at a given page. Citebite does this, however it links to a cached page instead of the act
There is an experimental feature in Chrome 74 called Scroll To Text Fragment which allows you to specify phrases to be highlighted in a URL. We may have to wait a while before this becomes finalised and supported in browsers by default.
Meanwhile, if the article to which you want to link also has a PDF version, you could use a URL like https://example.org/file.pdf#page=2&search=findme to highlight findme on page 2.
