TIFF is a very inefficient, HUGE format, with no compression.  GIF is best 
for black-and-white images, or 16 shades of gray.  On strictly 2-color (black & 
white) text and line drawings, GIF is 10x better than anything else.  

But scanned text, if in strict B&W, will be terribly broken up and moth-eaten 
or acid-etched looking, and lines will fade in and out of drawings.  So to 
permit "aliasing" which preserves the shapes, it's best to scan in 16 shades of 
gray, and GIF that.  Under some conditions, JPEG may do better than GIF, 
certainly for 256 shades of gray as would be used for photos.

Anyway, TIFF is good for temporary storage while you wait to do OCR or 
compression to GIF, but not for long term storage and certainly not transmission.
