Mobile Apps and Browser Extensions: Hypothesis Browser Extension/Bookmarklet

Hypothesis Browser Extension/Bookmarklet

What it does

Hypothesis is an annotation tool for websites. You can also annotate pdfs when viewed in your browser. Download as either a browser extension (for Chrome) or bookmarklet (for other browsers), sign up, log in, and start annotating the web.

This is a great resource for annotating ebooks or other e-content from the library. Just keep in mind that access to library resources ends when you are no longer part of our campus community.

Of note: this tool is integrated into AccessMedicine and AccessPhysiotherapy. When in a chapter, click annotate to prompt Hypothesis to open. See the example below.
