As recently reported on the VLLB, the Alberta Queen's Printer has announced RSS feeds for both their website and QP Source Professional.
Sheldon Staszko, Director of Alberta Queen's Printer, made the announcement via the Calgary Law Libraries Group listserv on July 27th. Alberta's QP is the first to deliver this type of service via RSS in Canada. How long until the rest of Canada follows suit, either Nationally or Provincially, is anyone's guess. Regardless, this is a great first step and definitely one in the right direction.
