The Asser series is the most important source of civil law in the Netherlands. The complete Asser series (+30 volumes) is available in book form in Law Library Limburg, but can also be consulted online in Kluwer Navigator via Maastricht University.
To log in on Kluwer Navigator: click on "Login voor WO/HBO" and then choose Maastricht University. Next click on "uitgaven" and then on "Asser-serie".
At the start of their first academic year law faculty students will receive a visitors card for the Maastricht University Library as well as an UM-account to get access to their electronic sources, even from home. The UM-card and the UM-account remain valid as long as these students are connected to Hasselt University.
More information about the UM-card can be found on https://www.maastrichtuniversity.nl/nl/file/3484/download?token=QMtrRyRl (pdf). In case of problems with your UM-account, it is best to contact the ICTS-servicedesk of Maastricht University (Servicedesk-ICTS@maastrichtuniversity.nl or 0031 (0)43 388 5555). In order to reset your UM-account, you will need to add a copy of your identity card.
