To find out whether you have been listed in a directory you could do the following:
Check your email regularly as 1 in every 3 directories send out emails acknowledging submissions made and some of them also send out follow-up mails informing you of whether your site has been approved
Check random directories for the presence of your link
Type in the following search command into Google:
(where www.abc.com is your URL ). This would give you a rough indication of the number of pages apart from your own, which have the word 'directory' and your URL mentioned in them.
Type this command into Google to check for your link in a particular directory:
(where abc.com is your website URL and xyz.com is the particular directory's URL).
