# Spectral Libraries

A number of spectral libraries have been include in `speXtra`.
See {ref}`database-contents` for a summary what is included in the database.

To list the names of the libraries included in the database

```{code-cell} ipython3
from spextra import spextra_database
spextra_database["libraries"]
```

To see which templates are available in each library

```{code-cell} ipython3
from spextra import SpecLibrary
lib = SpecLibrary("kc96")
list(lib)
```

Below you can find a detailed description of each library.
