Is any tool that can do that and specify the link depth? If so, I can read web content on my reader. I know RSS is possible, just wonder if there is any tool for normal web content. Thanks.

Instead of converting a whole website, I usually extract the right information using a content extractor like Dapper, and then generate a PDF out of the RSS output of Dapper.

You can hardly turn a full website into a PDF: you need to remove most of the layout, links etc... A tool that would convert "a full website", would be a content extractor too. That's why using a content extraction service or tool and then converting this information into PDF, you get the same kind of result.

Given that there's no facility on the Reader for linking between documents, you'd need a tool which converted the web site into a single "linear" document with the links jumping you around within it - ie something which "stiched together" the individual pages of the web site "end to end" into one single "page". That wouldn't actually be terribly difficult to do - I might have a go at doing something about it if I have some free time.

Also Adobe Acrobat in the more recent versions will allow you to extract full web sites or just down so many levels into a PDF. I do this for later analysis but these are letter sized pages. I see no reason you could not do the same with pages sized for your reader.

thanks, guys. I found that acrobat can do a really good job for online/offline website (See attached pic). The hyberlink is also working with sony reader. Dapper is a good idea (though i am not sure if you can use it for offline contents).

web2book/rss2book can also do this.

html2lrf

I tried that. It's great. Much better than Acrobat, because it generates native lrf format. Thanks.
