9.0A1. The rules in this chapter cover the description of digital resources (those that were created digitally, those that consist of digitized content, and combinations of the two). Digital resources consist of data (numeric, textual, graphic, cartographic, sound, video, etc.) and/or programs. Since digital resources often have characteristics in common with other media, consult other chapters in Part 1 as appropriate. The description of digital resources in a local physical carrier (CD-ROMs, computer tapes, etc.) and those available only by remote access (databases, websites, e.journals, etc.) differs (see 9.5).
