> Abstract
>
>
> Internet search engines function in a present which changes  
> continuously.
> The search engines update their indices regularly, overwriting Web  
> pages
> with newer ones, adding new pages to the index, and losing older ones.  
> Some
> search engines can be used to search for information at the internet  
> for
> specific periods of time. However, these 'date stamps' are not  
> determined by
> the first occurrence of the pages in the Web, but by the last date at  
> which
> a page was updated or a new page was added, and the search engine's  
> crawler
> updated this change in the database. This has major implications for  
> the use
> of search engines in scholarly research as well as theoretical  
> implications
> for the conceptions of time and temporality. We examine the interplay
> between the different updating frequencies by using AltaVista and  
> Google for
> searches at different moments of time. Both the retrieval of the  
> results and
> the structure of the retrieved information erodes over time.
