I was trying to run some notebook I downloaded from MathWorld, but lots of them need

<< MathWorldCurves


I tried to google it , only to find this, but the link links to nothing but a blank page. so where do I find these packages?

I never heard of it. Could you please specify which notebook was it you've downloaded from MathWorld and required the package? –  István Zachar Mar 8 at 8:38

Thanks. I guess it must be part of the list of server-side packages, like "UtilitiesLiveGraphics3D" in e.g. Slinky.nb. Best would be to write directly to Eric Weisstein, the maintainer of the site. If you do so and he replies, be sure to add an answer here! –  István Zachar Mar 8 at 8:47
They were there 6 months ago, I'd venture lost in the shuffle. Ping support and let them know. –  rasher Mar 8 at 9:08
