Google PageRank displayed in the green bar has been an illusive factor for most SEOs , while it doesn't hold much importance, most SEOs ( atleast during their formative years ) have been obsessed with it. Even the SEO pros take a look at the PR once in a while just to have some idea on how the page is doing.
There are multiple Google PR checker tools available on the web however for all of them you need to insert each URL separately to check the PR. Brandon Thomson has created a new PageRank Checker tool based on Google Apps, that can actually calculate PageRank of multiple pages at one go.
The users can either upload a XML sitemap or a Text file with all the URLs for which the Page Rank needs to be checked. In addition , this tool can also help to find PageRank of all URLs that are linked from a specified webpage. Indeed a nice toy for people who still run after that silly green bar
