Lending Library SDLTAP has a lending library containing both printed material and videotapes. Catalogs listing our printed materials and videotapes contain a short description of each item. Catalogs can be ordered from the SDLTAP office without charge. You may check out any videos or printed materials for two weeks by calling or writing to our office. The only charge for this service is a small return postage fee. Since you may return these materials using library rates, the cost is minimal.
