Methods for Collecting Records and Materials in the Republican Period             The archives accept  records and materials preserved by any organization and institution, social group, enterprise, and individual, who wishes to contribute them to the SHAC, after examination by specialists to assess their  value. The SHAC will adopt following measures to collect them:         1. To buy them for full or half price.         2. If owners wish to donate archival materials, the SHAC will hold a donation ceremony and issue a certificate of donation. Donators have priority in using the recordsthey donated.         3. Paid deposit in the SHAC. The depositors continue to hold the proprietary rights in the records deposited. No organization or individual can access or publish the records without the depositors' permission.         4. Exchange. SHAC will exchange important records and materials with other archives and libraries.         5. Replication. After agreement between the owners of records and materials and the SHAC, the SHAC will photo-copy, microfilmed, or scan the materials,and store them in the archives.
