Book on weak narrators?

[muslimforever2012]

Assalamu alaikum everyone.

Is there any online book or PDF that lists weak Hadith narrators and scholar comments on them? I found a similar one but it is only available in print.

Thanks.

I've never about a book like this but I know a guy who is really good at recognizing weak narrators as well as fabricators, i wonder how he does that, maybe he's really knowledgeable on hadith studies BUT i have vague memories of him commenting that he uses an Arabic website for checking Hadiths if I'm not mistaken...I don't have his personal email but you can still ask him by commenting on his blog, he always reply most of the time....
