This program searches only the slide rule sites listed at the end of this file.

On inputting the three search strings:

	1. dietzgen
	2. tyler
	3. multilog

into the search engine the following is typical output:

      http://sliderules.lovett.com/index2.cgi   Direct Link

By default the "First Hit on Each Page Only" was selected so that only the first hit
(of all three search strings) is shown. Note that all search strings are highlighted in red.

Each site found has two links associated with it; one at the top and one at the bottom and
both in blue. e.g.

David Crate's Quality Slide Rules
and
Direct Link

As its name suggests "Direct Link" is a direct link to the site shown in green, viz:

http://davidcrate.com/index.html

Selecting this link displays the page as written by its author. The search strings selected
are not, of course, highlighted.

Selecting the top link displays the selected page with the relevant search strings
highlighted in red. ** If there are many search strings to be higlighted, the display will
be significantly slower than that by clicking the Direct Link. **

Now I do not necessarily index the whole of a site. Some sites have significantly more than
slide rule content on them.

It was my design aim to attempt to restrict returned hits to slide rule related topics only.

I therefore only index content in the entry directory and all sub-directories of this entry
directory to which there are links. That is, my software assumes that sites are well
structured with all slide rule content appearing in the same directory sub-tree.

If this is not the case and slide rule content is scattered across a site then some
of it will not be indexed.

Further, only links met within htm/html/shtm/shtml files are followed.

It should be emphasised that this system does not scan the slide rule sites in real time.
Approximately every six months the system runs a web crawler (variously called bots,spiders,
webots etc., etc) which currently indexes over 40 slide rule web sites. It is this index
which is searched when you put in a request.

Here follows a list of sites which I currently index. More will be added as I become aware of them.

I welcome suggestions of sites for inclusion.

Sadly, there are one or two (non-English) sites of which I am aware that have not been included.
This is because content on these sites is wrecking the layout of my display. Possibly this is due
to unusual characters in the text. I am currently looking at this to determine the cause.

This is the list of sites I have indexed:
