In-Depth Information
we browsed from Science to Animals to Mammals to Lions. Using Open
Directory Project, the pathway looks like this:
Top: Science: Biology: Flora and Fauna: Animalia: Chordata:
Mammalia: Carnivora: Felidae: Panthera: Lion
I could get as far as Animalia if I were browsing, but ater that I'd be lost.
I thought a “chordata” was something you play on a guitar. I recommend
browsing through the categories until you're stumped. hen use the search
engine at the top of the page to search only within that category. From there
you're directed to the right places. Browsing and then searching is worth it:
as of this writing, the Open Directory Project has more lion pages than the
Yahoo Directory does.
hint
Let your queries get a little more general, but drill down as much
as you can into the directory structure before you start using the
search box. it will save you a lot of time.
Trapping
he ODP doesn't ofer RSS, nor does it ofer e-mail alerts. You have to
choose the categories you want and then feed them to page monitors.
Possibilities
he ODP is a little diferent from the Yahoo Directory. In addition to indexing
Web sites, it also indexes RSS feeds relevant to a category, as well as articles
relevant to a category. So when you're monitoring here, you'll not only be able
to keep an eye out for relevant and oten very credible content, but you'll also
learn about RSS feeds that contain content relevant to the category. For these
reasons, and because of the fact that I ind this directory in some instances
to be better populated than the Yahoo Directory, I recommend trying a few
extra categories here. he extra monitoring time will be worth it.
We've covered ive diferent directories and search engines here. But are
those all the possible ones? Heavens no; there are hundreds out there! To
cover them all would take up far too much space, but here are a couple more
that I think you should at least consider when you're preparing to trap the
general Web. I don't go as in-depth with these as I did with the irst-tier
search engines, but there's enough information here that you should be able
to do some experimentation on your own.
