PC-Blue, PC-Sig, CUG and other Soft Collections

I dedicated last days to search accross the Internet for the Pc-Blue, Pc-Sig, CUG, Exec-Pc , PcSoft, PcMagazine utilities, and other collections of software. My notices was about a growing difficult or even impossible obtention of some or even all of it. Well, I have some success in my search. By the moment I could locate these collections: * Pc-Blue almost complete, from vol001 to vol723. I should need to locate over 50 lost vols, mostly from the 500-723 group. * One cd-rom I've located talk about Pc-Red and Pc-Green. What the hell is this ? * I could obtain over 2000 vols. of the Pc-Sig collection, and I'm pending to purchase some cd-rom with parts of the collection availables in Europe yet. If I understand its way of work, one volume or disk could have diverse releases but keeping its physical identificacion (example: disk0001.zip). Is this right ? * I could locate too in some BBS and Planetmirror the first part of the CUG library, from volumes 100 to 500 or so. * About Exec-Pc, I only could have some success with some collections of games edited in form of magazine years ago. They are in some places related with games. * About the rest of Exec-Pc files I couldn't locate nothing with this name, even in the ExecPc BBS (by the way, I should like to know if the messages to the SySop arrives to him; I am pending to raise my level to begin to download some items, mostly of PC-SIG). * Finally, I couldn't locate nothin of PCSOFT items. I must review an old collection of over 150 Shareware CD's from the beginning/middle of the nineties. I'm almost sure they contains some of these collections and/or files. But all the help is welcome. My intention is classify all the files and store them in a manner similar to the old Simtel, Oak, Wuarchive or Cica servers did it. By the way, I think that someone asked for these items some time ago (Perhaps Gene for Retoroarchive...) Cheers Sergio
