Why should anyone bother? The database on frankenjura.com is complete and has search facilities vastly beyond the powers of UKC (and is in English).
In reply to UKC Articles:
The Frankenjura is much larger than described and starts south of Regensburg (there is a large sign on the motorway telling one so). For climbing purposes it is split into the Southern and Northern Frankenjura. Southern is the area south and west of Regensburg including the Altmuhltal, Donautal, Naabtal and a few others, altogether about 1800 routes. A generally more open landscape as the river valleys are wider and a more technical style of climbing with less finger pockets.
The Northern Frankenjura is the area described in the article.
The Röker guide is by far the best one even in German and is the only complete guide in English.
