Professional Astronomy without a Librarian

Virtually every serious'' place where professional astronomy is done has a librarian, even if shared with the physics or math department. Since its creation in 1994 of {\it Departamento de Astronom\'{\i}a} (DA) of Universidad de Guanajuato (UG) it was neither provided with a librarian, nor with proper space for its holdings, nor with a budget allowing institutional journal subscriptions. I describe my experience of now five years as amateur’’ librarian, and present information on other small astronomy institutions in Mexico in a similar situation.
