I don't know if you are aware but the CRNBC has learning resources publicly available on their website. The resources include; web learning modules, webinars, case studies, practice resources and can be used to meet the quality assurance requirements. Also, if you are a member of ARNBC you will automatically be a member of CNA and can have access to CNA's nurseone.ca which includes a library resource. You can also publicly access Ontario's RNAO best practice guidelines (you do not need to be a member). Also, nurses who are members of specialty nursing organizations often receive journals/newsletters related to their speciality and attend conferences. For disease specific information, nurses can use google to search Canadian resources for healthcare professionals. For drug or treatment specific information, nurses can search the manufacturer's company websites for their professional information. There are many ways for nurses to keep their practice up to date and continue life long learning, there is no need for regulating bodies to keep an underutilized, expensive library service for a handful of private practice nurses.
I am not sure how your comparison of BC's and Ontario's regulatory body registration and professional association membership costs relate to library services, can you explain? Nor do I understand what the BC nursing union suing the professional association has to do with library services. It is hard for me to understand the point of your disagreement when you seem to be throwing unrelated ideas together.
