Importance of Link Viability
​Curating online content for 25 years from a school website to Wikispaces to my own website L. Houle's Ed Tools, as well as my LiveBinders, it's been important that I keep all shared links up-to-date.  There is nothing worse than following a link and finding it no longer viable. Here on my site's home page and under each individual resource page I keep my viewers notified when I last updated and/or verified links. With my website integrated with my LiveBinders viewers can always see that information along with checking my binder descriptions. Over the years, adding and deleting websites based on availability, usability and alterations to a site have brought the list currently to 214 sites with 275 sites deleted over the years. 

Since it's not possible to check links within a binder, other than visiting each tab, my webpage links are my means for checking viability.  Anyone can design the means for checking resource link viability by creating a list whether it be in a doc published to the web or a list on a Google site, etc. can use one of these 3 to verify and keep things up-to-date. Note when you find a site that still has good content that 'doesn't age" consider saving it to the Internet Archive's Wayback Machine. Then add it to your list of URLs! (I love the resource, even have a copy of my original school website held for posterity!)

When a site does not respond, before you delete consider testing the URL with one or both of these sites I use to investigate.
