Abd ul-Rahman,
You suggest a fine idea but over the years I have come to one
conclusion about common user libraries. There are just too many unique details
that people want or have need of in their library parts. This includes but is
by no means limited to: Line thickness, pad sizes, in some cases pin numbering
(SOT-23 parts?), company part numbers/details, layer usage, parameters and
fields, just plain personal preferences and then we also fall prey to
fabrication issues with certain vendors.
I definitely don't knock your idea or enthusiasm for such a project but
for the aforementioned reasons I would abstain. This is why I also never use
any canned libraries (well very rarely use them as a starting template), by the
time I modify them and check their accuracy I usually can design them from
scratch in an equal or lesser amount of time.

Gradually, though, I'm hoping, the existence of
common library symbols/footprints/models may be finessing this problem.
I've argued that we should organize as users to provide this for
ourselves, since there is a clear common interest and it would not be
at all difficult to do; users are already building parts and testing
the symbols and footprints in actual use, there only needs to be a
way to collect the information and coordinate validation of it.
Fortunately, we now have wikis.... so this should actually be easy.

needs work; essentially, I can start things, seed them now, I can't
be the chief cook and bottlewasher. But many people putting in a
little time can sometimes accomplish more than a few people putting
in a lot of time....
