I while ago, I read through most of an English translation Rambam's Introduction to his Commentary on the Mishnah. I think it was an earlier edition of this one, but I'm not sure.
I'm looking for a good online version of the hebrew (either in download format or straight text).
I found this, but I don't know anything about its accuracy.
Some of the things I would prefer include:
Lots of references and sources
Clear and easy to read
If I have a choice, I would prefer something I can download (e.g. pdf).
I guess I'm looking for something close what is printed in the Hakdamot volume of the Rambam Leam.
