For large organizations, tracking and managing a library of sales and marketing materials can be daunting. Just like a library requires a taxonomy scheme for managing their constantly changing archive of periodicals, marketing departments require a similar system that can be easily indexed and cross-referenced. Enter the literature number ("lit number"), an alpha-numeric identifier that is automatically generated and attached to each document in a marketer's library. Think of it as the corporate version of the Dewey Decimal system. Most companies might not think their small library of corporate materials warrants such a system. But they would be mistaken. As organizations grow, so do the materials they use to support their sales staff, educate partners, and inform end-users. Lit numbers are the Rosetta Stone of the corporate library.
