You can now save links on Facebook to go back to later. Although they have a nice informational page about it if you know about it, it isn’t something you can yet search for in their help menu. It’s possible they are still rolling it out.
Although I can find references to it online in multiple stories and Facebook’s own blog, I can’t find their informative graphics anywhere. So, I snipped them so you can see them here.
Facebook has never been an especially good way to catalog information like that. This should make it much easier. Another option would be to use an application designed for saving things – like evernote.com. But if you want to keep the material on Facebook, now you have a convenient way to do it. Enjoy!
