::::::::There's another good section of WP:V, one of the three principal policy statements of the Wikipedia project. It's called WP:SOURCES:

Articles should be based on reliable, third-party, published sources with a reputation for fact-checking and accuracy. .... In general, the best sources have a professional structure in place for checking or analyzing facts, legal issues, evidence, and arguments .... Material from reliable non-academic sources may also be used, particularly if it appears in respected mainstream publications. Other reliable sources include university-level textbooks, books published by respected publishing houses, magazines, journals, and mainstream newspapers. 

Please explain Trine Day's fact-checking process to me, and post a few links demonstrating their reputation for fact-checking and accuracy. Prove to me that it's a "respected publishing house."
