Your options for linking students to online content are:
You can link directly from the course management system to online content in library databases by using the "permalink" feature in many library databases
You can manage all your links to library database content by using e-reserves
You can upload the article or chapter available via the course management system - however, if this material is available via a library database, best practice is to link to the content in the database (see #1 above)
You can always provide links to material that already exists on the Web, such as public domain ebooks or other web content
