Need help getting info on user readstatus updates

[Anna]

Hi, I'm absolutely new to Goodreads API, so I need some help. My target is to get all information on a particular user's updates to monitor the dynamics of reading status. I tried using user.show method, which returns an XML response with UPDATES field (update type='readstatus'). So far so good. But in the response I only see 9 most recent updates (while I know there are many more). And I can see no pagination option.
Is there a way to get more info on user updates, preferably for the whole period of the existance of the account?

UPD just in case:
failed to find a simple and beautiful API solution, so had to get down to hardcore web scraping.
But if somebody has a better idea, I'm really curious.

I'm also trying to find the answer to this question, but no luck yet!
