Too many DEC binders

[shadoooo]

Hello,
I also have a bunch of manuals, mainly for rt11, which aren't available in
bitsavers.
I always thought of bitsavers as the "whole" archive for DEC stuff, however
time ago, sorting these manuals, I found they where available only on Manx
or Antonio Carlini's archive.
Many manuals then are available on other sites, etc
Now the question: why collected manuals from other sites couldn't be added
to bitsavers too?

Thanks
Andrea
