To add an online article to Laulima, you need to find the permanent link to the article. Sometimes, that will be the link in the browser, but sometimes those links are not reliable and will be broken when students try to access the resource. You need to find the reliable link. "Share Link to Book," "Permalink," "Persistent Link," etc. all refer to the same function—different publishers use different terms.
Now, you can use that URL to add a resource to one of the Laulima tools, such as those listed on the navigation bar to the left.
It may be possible to create a Proxy Link so that students do not have to log in a second time to access the resource. Instructions are located in a module on the left. This process does not work for all vendors, so make sure to test your links.
