LLMC is a non-profit cooperative of libraries dedicated to the twin goals of, preserving legal titles and government documents, while making copies inexpensively available digitally through its on-line service LLMC-Digital. LLMC provides libraries with a reliable and budget-friendly source of digital replacement when their older, physically deteriorating books became too burdensome to store given diminished use. While aiding libraries in their preservation and space recovery programs, it also provides an economical way to complete retrospective collections.
