Until today, I've always linked to opinions in pdf form as posted on the court's own website. I did that because the opinions are available for free there, and linking to them added value for the reader. The essential value of blogs is in the links. Plus, the opinions generally weren't available for free anywhere else.
Now that has changed. Most court opinions are now available through Google Scholar, which raises the issue, should I link to the opinion on the court's website, or to the opinion on Google Scholar? I've decided to link to the opinion on Google Scholar, on the grounds that it delivers more added value for the reader. The Google Scholar version of the opinion will have hyperlinks to most of the cases cited in the opinion, which is very useful for anyone who has a professional interest in the subject. Also, the Google Scholar version has a tab where the reader can click to see how the opinion has been cited, which is also very useful.
I also find it easier to cut and paste from Google Scholar into a Typepad blog, than it is to do so from a pdf. There's less formatting to clean up.
The downside of Google Scholar is that it doesn't let you print out a clean copy of the opinion that would be appropriate, in my view, to pass up to the judge in a court. In other words, it will have the Google Scholar headings and such, which the court might find strange. In contrast, it would be more acceptable to pass up a printout of a clean pdf opinion from an appellate court's own website. On balance, that's not enough to not use Google Scholar.
As always, it is fun to blog about blogging.
