Ukrainian

Top Ping (Odessa, Kiev)

Probably the best Ukrainian catalogue. Lot's of information. Nice search engine. The only "-" is it's speed.

Alpha Counter (Kiev)

One of the first, good enough but sometimes unloaddable :)

Meta (Kharkiv)

This one is very good, and rather quick.

Poshuk.Dnepr (Dnipropetrovs'k)

Not too quick but it provides big set of links.

UA Hoo! (Kiev)

I remember it to be a convinient tool, but during last days I can't load it.

Brama (L'viv)

Really good English speakers' oriented guide to Ukrainian resources. Quick as well :)

Where to go? (Dnipropetrovs'k)

Russian language only.

Search Ukrainian Internet Resources (Kiev)

Very convinient and quick, but the database is not too vast.

Index99 (Kiev)

I don't know whether it's good or bad.

Village Index (Donetsk)

HMMMM... Weird one.

Ukraine.com (Somewhere)

Claims to be a big catalogue. I wouldn't call it such, but who knows, some sites are improving from time to time :)

French

Good one, a lot of services.

A bit worse, but their are partners with Voila :).

French branch office of famous Yahoo.

Russian

Simply the best Russian catalogue.

Never actually used it

A lot of services and a big catalogue.

Kyrill and Mythody

Look yourself.

Pretty quick and "user friendly".

International

Really big catalogue of newspapers/journals/magazines all over the world I liked it very much. When I first got there I've found several Ukrainian newspapers I had no idea of :) What to say about international resources!
