It doesn't quite sound like action is necessary either -- unless your boss expects you to read FYIs thoroughly?
If not, I would take a minute or two to look at the link; if it looks like information I will truly need in the future, I would save it digitally. Usually I would just bookmark the site. If it looks extremely valuable, I might save the web page to disk just in case the web page later disappears. Either way, bookmarked or digitally filed, I'll be able to find it again easily with Google Desktop search. Digital filing/indexed search retrieval is faster and easier than with paper, IMO, plus it saves valuable real estate space in my office and home. If the information doesn't look that useful, I don't save it at all, not even digitally.
If my boss expected me to read the information thoroughly, and it would take more than 2 minutes, I'd just add the action "Read X" to the appropriate Next Actions list. Some actions are truly one-offs and don't need a project at all.
