Welcome to hortensj-garden.org — a tiny knowledge park.
This portal provides easy-to-use hierarchical access to free geographical, linguistic and encyclopedic information resources.
This portal is implemented by means of three software products developed at the hortensj-garden-labs: TreeViewer, PlusUltra and puTiler. All rights reserved.
This is a private and completely independent project: no political, economic, religious, academic or other organisation stands behind us. Donations are welcome.
