Recently, we have updated design of the website and moved it to WordPress. We are now reviewing all catalog entries to verify that all the descriptions and categories have been transferred to the new website correctly. At the same time, we update/delete broken URLs and expand resource descriptions with additional information and screenshots, if it helps understand value of the resource better.

Should you find an error in the resource description or categories or if you encounter a broken URL, please send a note to us using the link 'Report' just below the resource description, next to the author name.
