I have watched Warehouse 13 and am now watching The librarians because the sci-fi meets history aspect is great. But I noticed the similarities: Storage facility for the supernatural and the history it has intertwined with the world history. Responsible for the safety of the world. and the guardians/servants of the facility are chosen by the facility and don't believe in the power but then get used to it. Secrets and magic and science and sarcasm.
Is there a book or movie that started the genre, or was The Librarian the first of the genre and Warehouse 13 picked up where the original movies fell flat.
