Still confused?

Check out The Cornell University Library for a check list of questions that can help you decide.

Can someone please just tell me if this is a reputable site?

Want a website that ranks the credibility of other web pages?  Type in your website URL and see how the DMOZ people classify it.  Is it trash or is it treasure?  Check it out. 

Where can I find out who the publisher is?

Find the copyright symbol.  (Usually it is at the very bottom of the web page).

After the copyright symbol is the copyright date.  The publisher's name is after the date. 

See this example:  © 1996–2013 American Library Association.

In this case the publisher is the American Library Association.
