I have found that some university libraries take the output from the
copying machine directly to a PDF or other file type that can be
captured on a memory stick, or if you are a student you just email it to
yourself to eliminate paper copies. I find this a very handy feature so
I do not accumulate a large stack of photocopies to take home and file.
Unfortunately I couldn't find a "descreen filter" in the copy machine
options when copying photos in railroad journals. Do some machines copy
machine have this option? The "photo mode" didn't "descreen" the image.

not aware that the scanners had a "descreen filter" which (I looked it
up on Google) eliminates problems you may get from scanning printed
materials that have halftone dots. Since many of us do scan reference
materials this information may prove to be useful.

I concur. Digital bits take up very little space! Just use the
"descreen filter" on your scanner and put something dark behind
the page to limit bleed-through. And you can sell the magazines
at a flea market instead of throwing them out.
