The legal source texts are an essential didactic tool in the teaching history of law. The students should not only read texts, but they should look for the specific information in them, interpret and analyse. Working with the source texts with the students has a different aim than in the historical studies. It serves to legal interpretation of the regulations, that were in force in the past. It replaces the external and internal 51 criticism. For the teaching of the legal history, it is important that the editions of the legal source texts should include the examples of administrative and judicial application of law and the regional aspect (so interesting for students).
