African History
There
is no date on this site. But you should consider whether a date is
really necessary for this subject. As the subject is history, you
may not need a current date.
But if you were working on a paper about recent history, a current
date could be important.
If you
are not sure whether this source is reliable because of the missing
date, consider the other evaluation criteria.
2.
Animal Rights
There is a copyright date from the year 2000 at the bottom, but no
update date.
You could follow the menu point "Events/News." The latest
event they announce is for September 2005.
You could also check the links on this site and see if they are current
and if there are many dead links.
Be cautious; if you find many dead links, that means that nobody has
checked the links for a while and indicates that the content of the
site is probably not very current.
3.
Census Pennsylvania
The important
data here is at the bottom of the page: they clearly state where the
data is derived from, including the time period.
This is important for you to know if you are doing research on the
census for this specific time period.
This
site has a fairly current update date, but that does not mean that the
data is current. The data is still only valid for the time that is
stated next to the information.
4.
Child Development
Here
you have a copyright date with beginning and end.
You also find the exact time when the site was updated.
The dates are in this case in the middle of the site, but the publisher
made it easy to find them because through the layout they clearly
differ from the rest of the site.
This is not always the case; on some sites you really have to search
for any dates.
You cannot know to what extent the site has been updated. Maybe only
a part has been updated, or they just changed something in the layout.
5.
Law and Economics
There
is a copyright date at the bottom of the site with beginning and end
date.
This copyright date ends in 2000.
On this site you have to look round a bit for a revision date.
There is a revision date under "Search the Bibliographical Database"
which says that that feature was last updated in 1997.
Be aware that this date is old and the content of the site may be
outdated.
6.
Opinion Poll
Here
you find different dates:
The copyright date, which is at the bottom of the page.
In this case, it is the copyright date for the current year, so
you do not know when this site was first put on the web.
Dates for the several opinion polls.
When you click on one of the links, you can see on what day the
opinion poll was done, or during which time period.
It is really important to have exact dates for polls, because it enables
you to draw conclusions.
