Why: Preservation (?) Well, not yet … the current state of technology does not allow for the projection of the longevity of digital assets at the same levels as is possible for print and microfilm. Any conversion from analog (e.g. print) to digital will have some level of loss of fidelity. However, potential decreased reference to print copies, will reduce wear and tear on the originals.
Digitized collections allow for the creation of finding aids, links to online catalogs, full-text searching capabilities, structured metadata, and other methods of providing “content control” of the collections.
Conversion from an analog format (text, graphic, analog audio/video, etc.) to a digital format based on a binary series of “1’s” and “0’s”
To translate into a digital form. For example, optical scanners digitize images by translating them into bit maps. It is also possible to digitize sound, video, and any type of movement. In all these cases, digitization is performed by sampling at discrete intervals. To digitize sound, for example, a device measures a sound wave's amplitude many times per second. These numeric values can then be recorded digitally.
What: Video "Doratopsis" paralarvae of Chiroteuthis. These specimens, the first with complete tails, show remarkable interspecific differences in tail morphology but little intraspecific variability. Eleven Pacific specimens had very long rigid tails characterized by pairs of large, fluid-inflated lateral pouches separated by 4-6 flat, rounded, lateral lobes of tissue (referred to here as flaps, not finlets).
What: Born Digital An increasing number of resources are now “born digital”, that is having no other existence than the online environment. These resources, often composed of elements of the materials just mentioned, share the same problems and benefits.
