I highly recommend viewing this YouTube video ... https://www.youtube.com/watch?v=7y9GAn5KF4E 'Using Zotero and Freeplane for research' He started using Freeplane (a mindmapping tool) to record his web and business activities, then later added Zotero to extend its capabilities. Both Freeplane and Zotero are open-source and free, and each have their own Wikipedia entries. From his YouTube video, follow his channel to get several more useful tips. I maintain my Web activities chronologically in a very large single mindmap, and occasionally export interesting chunks to new mindmaps specialising in a particular category. Or zip up a small map (readable text html) and email it to a friend/colleague. The map can be searched to quickly locate any page that was annotated eg 'codeproject' or 'raspberry pi'. Graham
