LDC members enjoy the following benefits:
Economical access to an extensive and growing catalog. LDC's Catalog  is unmatched. It spans more than 20 publication years and 30 to 36 new resources are added annually. Membership fees are low relative to data development costs making membership the most economical way to obtain multiple corpora from a given year or to license older data sets at significant discounts (up to 50%).
