To Joel Goldfield's question on file compression utilities: on a Mac I have
found Autodoubler (companion to DiskDoubler from Salient software) very
effective. It does not compress files at time of saving, but you can tell it
how much of the hard disk you want kept free and it will get to work on
compressing files when the machine is idle, after whatever interval you choose
If you want it not to compress particular files, you can exempt them. I don't
know if it is available for PCs.

Data Compression:
Stacker is a jim-dandy program for harddisk compression. On a 40 meg
laptop or desktop you can look at 78-80 meg when stacked. It makes a
disk within your disk and gives about a 2:1 ratio on most files. Less on
.exe files, perhaps 4:1 on dbase and graphics, depends, but in general it
doubles space. There is real change in speed of access and everything runs
and looks the same. However it does use up some of your memory as it runs.
Version 2.0 uses less than 1.0 did. I don't know if it lets you turn 120 meg
into 240 but 40 goes easily to 80. Diskdoubler is another program, but most
are based on the same techniques. The reviews in PC Mag gave Stacker best and
pointed out that the software version was close to as fast as the more
expensive software/hardware combo they also make. Just go the software route.

This is a bibliography program with a companion progam called
The Data Magician which transfers data "between various database,
text-base and library automation systems."
Has anyone had any experience with this program, especially
comparative experience? Specifically, how does it compare with
Pro-Cite? It claims to be able to transfer MARC-format records
downloaded from OPACS into text-base systems. Does it solve the
problem of downloading itself?
