# Selecting an Assembly
Choosing an ***Assembly*** from the drop-down list at the top will display the associated library files in the panel below. Assemblies are named by the species and the build version (e.g. Homo sapiens (human) - hg38). Different build versions for the same species are regarded as separate assemblies (Figure 1). Administrative users can delete a selected assembly by clicking the **bin** () icon.
Figure 1. Human assembly versions hg19 and hg38 will appear as separate assemblies in the drop-down list.
