oh ! …and one more thing, Theodore !
I do not very well understand the technical considerations you bring up in your message, such a thing not being my bag, but I understand you are looking for an RSS feed ?
« I haven’t found a way to access the whole catalog through an RSS feed or something similar,… »
I am not sure whether that means that you looked up our RSS feed and found it to be incompatible with your proposed application, or whether you simply overlooked it. In case of the latter, we DO have an RSS feed. You will find a link to subscribe to it in the rightmost column on the LA.com welcome page, about one screen down.

At the very least, this will keep you posted as to all new publications, as they become available to the public at large.
Hope this helps,
take care,
