I thought it would be easy to find a compilation of transistor data
listing the basic parameters (VCEmax, hFE, VCEsat, Pmax, fmax, ICEmax,
etc), for at least the basic types (2Nxxxx, BCxxx).

Of course most of the
google results are zero-information pages from darned component brokers,
but even after filtering those, I couldn't find any complete data.

best I could do was a list with decent amount of parameters but limited
coverage, on http://sound.westhost.com/trans.htm, and more comprehensive
list with just basic parameters at http://www.qsl.net/yo5ofh/data_sheets/
transist.txt .

Are there other sources that I overlooked? Perhaps one can do parametric
search using publicly available component libraries like LTspice?

Yes, I do realize that one can find the individual datasheets. I was
looking for a compilation of the data, for instance to sort it by the
saturation voltage and/or by speed, to find the best switchers. It was
a surprise to me---are not the standard type designators (e.g. 2N2222)
supposed to refer to 'identical' parameters? and if so, I am somehow
surprised that there isn't a list somewhere, just like there's a list
of 74xxxx TTL chips.

Individual manufacturers (IR for instance) have parametric searches for
their own product line that may even show rough pricing, but you just
have to know which ones are worth searching in. This newsgroup quite
often carries dialogs like
"I am using the xyz part, but it doesn't do abc"
"Try the uvw part, it has a higher fghi and is cheaper"
which is great if someone has the answer, but is so... manual.. and
even then the well-informed people are sometimes suprprised by new parts.

I could almost see a giant datasheet-scraping script that collects
this information continuously into a large table on the web, but then I
think of all the crazy formatting variations of datasheet tables and I
snap out of it.

This is almost as much use as the T.D.Towers publication.

blank lines are playing hell with function - not to mention the line
