Today on my way back from office, I touched Urdu bazar Karachi there I bought TIME ALMANAC 2008 powered by Britannica.com for rupees 500 (after bargaining) from some dictionary and journals shop, that is still packed, as i believe almanacs are good, in fact I wanted International "Economist" annual special issue 2008 that is due in the first week of December, things you are looking for are pretty nicely organized in that, find that in "Variety books" or "Galaxy" (both near liberty market) if you are in Lahore, and if in Islamabad check Saeed book bank, you 'll get that for rupees 300 only. As for the sites I have collected, in-numerous are saved as bookmarks, i need sometime to find the relevant.
