After the digital objects have been identified, acquiring them is the next step. Obviously, this is highly dependant on the source the material is acquired from. However, methods can be basically discriminated in passively accepting submissions, as addressed in Section 2.2.1, or actively collecting the digital objects, which is discussed in Section 2.2.2. Arguments on the way the data is acquired have to be carefully weighed when the archive is initially set up. Eventually, the accuracy and completeness of the collections depend on this decision, and changing to another approach could demand major restructuring.
