• Resumen

  • This article describes the results of a survey investigating the use of technological protection measure (TPM) tools to control patron access to or use of digital cultural materials made accessible by U.S. archives, libraries and museums. Libraries reported using a broader range of systems than archives or museums including repository software, streaming media servers, digital library software and courseware. In terms of controlling access to collections, most respondents reported using IP range restrictions and network-ID based authorization systems. Some reported restricting access to approved terminals or individual user registration systems. In terms of controlling use of collection items, respondents reported reliance on resolution limits, clips and thumbnails, and visible watermarking. A lower percentage reported use of click-through license agreements. Few institutions reported using new technologies to control access or use such as pop-ups, disabling right click copy and save functionalities, invisible watermarks, viewers or cross-institutional authentication systems.
