Here is a recipe on the web:
https://github.com/olek/calibre_readability
The description says that "currently" the recipe works for more-than-one-page-articles only if you send them to readability after choosing the "print view" option. I don't know whether this still holds true after the updates as I just tried sending 28 articles on readability (saved without having chosen print view) and it worked fine.
Yet, the Readability recipe is not still in the calibre recipe list; so there may be something wrong with it. If that is the case, I second the wish for a fully-working readability recipe.
