The article analyses the museum conceptions of Paul Otlet and Otto Neurath, which can be considered exponents of the Bibliographical Movement, a movement arisen in the transition of the 19th century to the 20th century that sought the organization of the recorded knowledge to its dissemination, access and use. The museums created by Otlet and Neurath are analysed, as well as their museological projects that weren't implemented and the mutual influence between them, highlighting as principles of their museological conceptions the importance of the social role of museums, visualization and the precedence of the ideas conveyed to the public by the institution instead of the originality and rarity of the objects displayed.
