File Sharing with Other Users |
Multiple users can access the same documents at the same time. |
Additional viewers limited to the number of rolls of film produced. |
One user at a time. |

File Sharing with Non-users |
An e-mail option is available. It allows the user to attach documents as PDF files to e-mail. Anyone who has access to e-mail should be able to download a reader that will read PDF files. Adobe Acrobat Reader is FREE. |

Indexing |
Documents can be indexed on multiple fields and the indexes are kept with the documents |
Documents can be indexed on multiple fields; however, the indexes will always be on another media. |
Documents can be indexed on multiple fields; however, a separate database is required or a paper print out. |
|
Searching Text |
Searches can be done using any combination of index fields and actual text contained in the document. |
None available. |
None available. |
|
Long range Availability |
The software used to access the images is burned on each CD produced. Therefore, as long as CD readers are available the images will be accessible. |
A microfilm reader (or reader/printer) will always have to be maintained. |
Files become cumbersome, but otherwise always available. |
|
Migration |
Documents are scanned as Tiff Group IV images and text is stored as ASCII files. These are basic, commonly used computer file formats. |
Specialized reader/scanners are available that will read the image from the film and scan into a document imaging system. |
Not Applicable. |
|
System Security |
A security system controls what folders and documents users can see, and what actions they can perform on live documents. Once files are burned to a CD, they cannot be deleted or altered in any manner. |
Once committed to film an image cannot be altered. Anyone who has access to the film and a viewer can view images. |
Anyone can have access to the documents. |
|
Safeguards |
Documents are kept "live" on a RAID server. A tape back up is run daily. Once a volume is full, two CDs are burned. |
Usually, two rolls of film are produced. One is retained by General Services and one is delivered to the department. |
None. |
|
Cost |
Imaging is slightly more expensive than microfilm to produce (usually less than one cent difference per image). No special equipment required to view. Cost to store is minimal. |
Microfilm is slightly less expensive than electronic imaging. Viewers or Reader/Printers are necessary to access images. Cost to store is minimal. |
Storage space can be one of the most expensive costs of doing business |
|
Durability of Media |
CDs can be kept virtually anywhere. Hazards are scratching and extreme heat. |
Film should be kept in a climate-controlled area, away from magnets and diazo duplicate film. Hazards include scratching, fire, and accidental erasure from exposure to contaminates. |
Paper hazards include fire, flood, misfiling and original documents not being returned. |
