Web Archiving
Texas Digital Library offers its regular members a 10% discount on Archive-It Membership. As we add more members over time, that discount could increase. To become part of the Archive-It consortial discount, contact the Archive-It team at the Internet Archive to discuss your level of membership, let them know you’re part of the TDL, and we’ll go from there. Once you join, your billing will be included in your annual membership fees with TDL and all hosting and support will be provided by Archive-It.
