Addresses from the previous version of OleaDB — the ones still saved in bookmarks, cited in papers or listed by search engines — had been leading to an error page. They now lead to the right record.

The old pages identified a cultivar by its name rather than by a number, and those names survived the rebuilding of the archive: this made it possible to find the corresponding page and send visitors straight to it. Where a name cannot be matched, the site now says so and offers the search, instead of leaving the visitor on an error.
