MOBIUS is a consortium of libraries in Missouri and several nearby U.S states.
The name was originally an acronym for Missouri Bibliographic Information User System,[1] although the organization no longer uses it as such.
The Tulsa City-County Library system became the first out-of-state member in 2014.
The MOBIUS Union Catalog includes over 29 million items.
Member libraries extend into Oklahoma, Iowa, Kansas, and Texas.
