Because CDs and DVDs contain multiple files, it makes them more difficult to make available in the digital library. The easiest way for us to provide you with the information on each is to compress all of the files into one, called an ISO image.
The Digitizing Process: Here's what we do to make these available to you!
STEP 1: Create an ISO Image.
Using LCISO Creator an ISO image of the disc is created and saved in the server.
What is an ISO Image?
From Wikipedia, the free encyclopedia
An ISO image (.iso) is a disk image of an ISO 9660 file system. ISO 9660 is an international standard originally devised for storing data on CD-ROM. More loosely, it refers to any optical disc image, even a UDF image.
As is typical for disc images, in addition to the data files that are contained in the ISO image, it also contains all the filesystem metadata, including boot code, structures, and attributes. All of this information is contained in a single file. These properties make it an attractive alternative to physical media for the distribution of software that requires this additional information as it is simple to retrieve over the Internet.
Some of the common uses include the distribution of operating systems, such as Linux or BSD systems, and LiveCDs. The ease of Internet transmission also makes the .iso format a common format for distributing copies of video games over peer-to-peer networks, such as BitTorrent or DirectConnect.
Most CD/DVD authoring utilities can deal with ISO images: producing them either by copying the data from existing media or generating new ones from existing files, or using them to create a copy on physical media. Most operating systems (including Mac OS, Mac OS X, BSD, Linux, and Windows with Microsoft Virtual CD-ROM panel) allow these images to be mounted as if they were physical discs, making them somewhat useful as a universal archive format.
Console emulators, such as ePSXe and PCSX2, and many other emulators that read from CD/DVD, are able to run ISO or BIN/CUE (and other similar formats) instead of running directly from the CD drive. Better performance is achieved by running an ISO since there is no waiting for the drive to be ready and the hard drive I/O speed is many times faster than the CD/DVD drive. Along with the ability to avoid disk failure (Shattering) which may be expensive to rectify.
STEP 2: Create Zip Folder.
The files of the CD or DVD are also saved in a compressed, zipped folder in the server.
STEP 3: Catalog.
The CD or DVD is cataloged in the CyberTools digital library and given a hyperlink to its saved files.
Downloading the CD or DVD:
Each item that has been digitized will have a link that looks like this:
Click here to access CD files. (Not a hyperlink.)
Clicking on the link will open the following page:
This page gives you two options:
1.) Download the ISO image file to your computer.
Select "Click here to Download" to download the ISO image to your computer allows you to burn the image to disc. In order to burn the image to disc, you will need to have burning software.
The recommended disc burning software is:
Nero Burning ROM at http://www.nero.com/eng/downloads.html OR
Roxio/Toast (for Mac) at http://www.roxio.com/enu/products/toast/titanium/overview.html
2.) Download the compressed zip file to your computer.
If you would like to save the zip file to your computer, select "Click here to Download a compressed (ZIP) file". Once the file is saved to disc, you should be able to access the files. If you have difficulty opening the zip folder, you may need to download a compressed file handling program.
The recommended file handling programs are:
Power Archiver at http://www.powerarchiver.com/download/
WinZip at http://www.winzip.com/index.htm
Stuffit Expander (MAC) at http://www.stuffit.com/win/expander/index.html
NOTE: CDs and DVDs may be purchased through NCRTM. See Ordering Materials for more details.
