Obtaining Data

The easiest way to access data is to become an LDC member. Membership offers organizations unparalled data rights and privileges (and discounts). Visit Membership Benefits to learn more. 

Licensing Data as a Member

Members can login to their LDC accounts to request data. When data is added to your cart, you will be presented with a click-through version of any applicable user agreements.  Any additional fees will be calculated at checkout. Payment can be made online by credit card or by one of the payment options listed below.  For further information, consult the Online Transactions page.

Licensing Data as a Nonmember

Most corpora distributed by LDC are available to nonmember organizations under research-only licenses and are subject to a nonmember license fee. Refer to the Catalog for corpus-specific nonmember license and fee information.

Data can be licensed through your LDC account. Nonmembers can create an account or login from the User Login page, the LDC Catalog, or LDC Online. When data is added to your bin, you will be presented with a click-through version of all applicable user licenses.  Licensing and any shipping fees will be calculated at check-out. Payment can be made online by credit card or by one of our other payment options listed below.  All necessary user licenses must be signed and payment made before an order is processed. For additional assistance contact the Membership Office.

Members-Only Corpora

Designated 'members-only' corpora are available to current members who can request the data at the listed reduced-license fee.

Nonmember User Agreement(s)

Most LDC corpora are governed by the LDC User Agreement for Non-Members; some corpora require the execution of specific user licenses. Each corpus catalog page contains a link to the required nonmember license agreement.

If not ordering online, fax signed licenses to +1.215.573.2175 or scan and email them here.
