IMAGE ARCHIVING: If the number of full-sized VO images and records becomes substantial, it is worthwhile to consider optional, alternative long-term storage / archival media to the computer hard disk. These include qic-80 format hard-disk-backup tape backup drives; "zip"-type removable floppy disks and floptical (writeable optical) disks. A twenty dollar 100 -135 mbyte "zip-type" [reuseable] disk can easily store a full year of VO records for a moderately busy practice. [For large .bmp format VO image databases, CD-ROM disk writer/readers are available for under $1000 with WORM {Write Once Read Many} media available at $10-15 per disk.]
