Useful Apps for Your Library

We now have, by virtue of the Internet, enough links about apps to keep us searching for what we need for a very long time. Searching for “Librarian’s note-taking app” gives a result of 3,400,000 items. I don’t think there’s time to look and try out all of those. Of course, each of us have different needs for which some apps might be useful, but our particular way of working doesn’t fit the way the app wants us to work. So is it trial and error that we use apps? Do we get friends to suggest a good app for us?
