Answer:
Audiovisual materials, such as videotapes, DVDs, audio tapes, audio CDs and microforms, can be difficult to identify and access. Microforms (microfilm and microfiche) are a means of preserving and distributing copies of information sources.
Explanation:
Audiovisual materials, such as videotapes, DVDs, audio tapes, audio CDs and microforms, can be difficult to identify and access. Unlike books and journals, which are covered by regular bibliographic tools, audiovisual materials are not systematically covered. Audiovisual materials are particularly important in educational environments, with university and school libraries generally holding strong audiovisual collections. Increasingly, audiovisual materials are available through the open web, although much material has been placed on the open web without the copyright owners’ permission, and users have to be cautious about downloading and using material, and particularly about passing audiovisual materials on to third parties, such as students in a class.
Microforms (microfilm and microfiche) are a means of preserving and distributing copies of information sources. Many libraries hold backruns of newspapers in microform in order to save space and because microforms are less likely to degrade than newsprint. In the twentieth century many libraries undertook microfilming projects in order to preserve valuable materials, although in the twenty-first century digitisation is becoming an alternative way to provide access to materials without the risks associated with users handling the originals.
