What should be linked Shortcut: WP:ELYES
1. Articles about any organization, person, web site, or other entity should link to the official site, if any. 2. An article about a book, a musical score, or some other media should link to a site hosting a copy of the work if none of the "Links normally to be avoided" criteria apply. 3. Sites that contain neutral and accurate material that cannot be integrated into the Wikipedia article due to copyright issues, amount of detail (such as professional athlete statistics, movie or television credits, interview transcripts, or online textbooks) or other reasons. 4. Sites with other meaningful, relevant content that is not suitable for inclusion in an article, such as reviews and interviews.
The specific pages that were linked came from and were cited as such. Reference materials and so forth.
