Information about me are displayed on search engines
The information displayed in search result at search engines are stored in the search companys (i.e. Google, MSN, Yahoo) database. This means that there are no direct link between the informatione stored at kurslitteratur.se and the information stored at the search company.
It can take some time between the removal of your ad att kurslitteratur.se and the removal of the same at the search engines. This means that the information can be found at the search engines despite the fact that the information no longer exist at kurslitteratur.se. The next time the search engine visits kurslitteratur.se to update their database it will be told that your ad is removed.
There are in other words no direct possibilities for me to remove information at search engines.
