ArcLib provides a comprehensive range of information services to architecture and design groups.

The ArcLib Online Database is a very large directory to architectural product trade catalogues and their supplier companies. Subscribers search by keyword for the product suppliers' catalogues.

Large Architectural Practices & Construction companies often use the database to manage their own libraries and contact lists and to record in-house knowledge about products and suppliers.

Designers and specifiers use it daily to:
* find alternative suppliers for a particular product
* locate supplier websites and phone numbers
* find information in their own library collections

As of September 2006, the Building Product Directory holds 4589 Suppliers of building products of interest to Australian architects, interior designers and builders.
