Ubuntu – How to check if a package is installed (no superuser privileges)

package-management

At our university we can get almost any ubuntu package installed we want, but we are not superusers ourselves (we need to request packages being installed).

With some libraries it is not always easy to know whether the package is already installed or not. Is there a simple way/command to check this?
