The Oregon Secretary of State updated their website not long ago and now the Archives webpages where you will find Legislative Records has a new URL.
If your own website or Favorites list has the old URL, you might want to update it manually, but the search engines catch up fairly quickly. (We have a lot of research guide and website updating to do ourselves. Oh boy.)
One’s quixotic search for PURLs (persistent uniform resource locators – see also the Wikipedia article) is foiled again. It takes research, time, expertise, and money to transition to PURLs and no one has that nowadays so most of us are stuck with link rot.
