You can access databases with your student account or LUCAT-identity.
To get to the login please go to Databases A-Z (link is available at the bottom of this page), search for the databases and click on the database title to get to the login page.
If you're not a student or researcher at Lund University you cannot access the databases from home (due to licensing restrictions), but you are welcome to use them when sitting on a computer at one of the libraries at Lund University.
