Glottolog 2.3 is out and a minor update of WALS
Last week has seen updates for two of our flagship datasets:
Glottolog (our comprehensive language catalog and bibliography)
WALS Online (the World Atlas of Language Structures Online).
While we would like to stick to a quarterly update schedule for Glottolog, last week's
update was in fact the first one in 2014. Thus it incorporated quite a few corrections
proposed to the editors over the last months.
An overview of the changes is given in Glottolog's new
We also included bibliographical records for
ISO 639-3 change requests
references in Glottolog.
In addition to the updated dataset, this Glottolog release includes some new functionality.
- New tree view
The old visualization of a languoids classification was difficult to navigate; in
particular it was not possible to compare a given languoid to others in different
branches of the same family tree.
This problem has been addressed by a new tree view (see for example the page for the
- Flexible language maps
It is now possible to display the languages from the

shows all languages in an area of the world bounded by the geographical latitudes 10° to 20° and
longitudes 10° to 30°.
- Country maps:
A special case of the language maps are maps for languages spoken in a particular
country. To display such a map, select a country from the
languoid search form and hit submit.
As an example

Compared to the changes in Glottolog, the update of WALS was rather minor. For a list
of changes, see the corresponding
issues on GitHub.
Following our distinction between WALS core data and auxiliary data, changes in datapoints
(i.e. in the coding of languages for features) are traceable from the datapoint pages
(e.g. Datapoint Latvian / Tea), while
for information like language classification we only display the current state.
