The Museo del Traje Library is a member of the Network of Museum Libraries (BIMUS) and its collections are integrated into its collective online catalogue.
Likewise, the Library also has digital copies in the Virtual Bibliographic Heritage Library with a portal of its own dedicated specifically to Museum Libraries dependent on the government body, Subdirección general de Museos Estatales.
The antique collection of the Library also forms part of the Catálogo Colectivo del Patrimonio Bibliográfico Español. The objective of this catalogue is to identify and locate bibliographic collections belonging to Spanish libraries, which because of their age, uniqueness or wealth, form part of the Spanish Historical Heritage.
