I had the same problem with UUCP201.LBR. Meanwhile,
 UUCP20I.LBR is available at SIMTEL20.
Trying out that (new?) version I found that the missing components
(ALL.SUB, OTHERS.SUB, CCICO.SUB and MAIL.SUB) were in place now.
Instead the docs are packed in a strange way, they are not crunched or
squeezed, but have the character 'Y' as the middle char of the file
extension ( *.DYC). What does this mean? A new reducing technique?

Yep, there's a new algorithm out there.  It's a program called
"CRLZH11" which uses the new LZH algorithm for tighter packs.  I
can mail you a copy of the uncruncher, UCRLZH11.COM, which will not
only uncrunch LZH-encoded files, they can uncrunch GEL-encoded
files (?Z?), and unsqueeze Huffman-encoded files (?Q?).  Plus I
have a file that can extract files from a library, while, at the
same time, decompress them if they are compressed.  For anyone out
there, jus give the word, and I'll post the LBR uuencoded, so you
can pipe it to uudecode.

This is indeed a new compression method - to uncompress it look for
CRLZH, or EXL: both of these will allow extraction of the file. .?Y?
and .?Z? are the current best methods, in 90% of cases I've tried,
.?Y? files come out smaller than the corresponding .?Z? file.

     There is a new compression algorithm available for CP/M machines
now.  The popular name for it seems to have become CRLZH.  This is the
same algorithm used by LHARC and PKZIP IMPLODE technique.

     Look for CRLZH11.LBR on your favorite RCP/M, or call Z-Node #9q
at 619-270-3148.  That's the author's own system, and the latest versions of the programs are available there.

Hello Ruediger,

the files with the "?Y?" extension are LZH compressed files (as ?Z? are
crunched and ?Q? are squeezed). I've got some programs to deal with these
files, if you are interested...
