+
+## Changing the Default Author and Title Sort
+
+Under `Preferences` and `Tweaks` the corresponding settings to change the title
+and author sort name can be found.
+
+`Author sort name algorithm` defines the author sort name.
+By setting `author_sort_copy_method = 'copy'` the author sort name is the same
+as the author name.
+After this setting has been changed right click `Authors` in the navigation bar
+on the left side and press `Manage Authors`.
+Then press `Recalculate all author sort values` for the change to take effect.
+
+`Control sorting of titles and series in the library display` defines the sort
+titles.
+Setting `title_series_sorting = 'strictly_alphabetic'` will use the standard
+title and wont make articles of titles suffixes.
