Thanks for raising this.  We should have some more helpful guidance,
and that might help encourage people to add a link.

I don't think we have an explicit licence on it.

It was actually drawn in a "xapian logo competition" by a tweakers.net
user, and I don't think a licence was specified.  We really should have
picked up on this at the time - I did try to make contact later but
failed.

It's probably reasonable to assume that it was provided to us to use as
a logo for Xapian, but I'd certainly be happier with an explicit
licence.

I've just done a quick bit of internet stalking (um, I mean sleuthing)
and I seem to have found an email address for him, so I'll try to
contact him once I checked I remembered the right user name.

I guess we should think about what licence is most appropriate.  I don't
think we want to demand verbatim use, but also I'm not sure a completely
liberal licence is appropriate for what is essentially branding.

Jenny Black drew this SVG version a couple of years ago, which should
be good for making resized bitmap versions, and for different
backgrounds:
