What you need is a copy of the FIA Year Book of Automobile Sport, generally referred to as the "Yellow book" because of its colour. For example Abebooks list a few.
Beginning in 1968, the FIA began issuing the Annuaire du Sport Automobile/Year Book of Automobile Sport, (the "Yellow Books") which contained the sort of information for which you seem to be searching. Prior to this date, such information was usually found in the annual publication of the Sporting Code and periodic bulletins issued by the CSI. Some of those here have copies of both the Yellow Books and some of the other CSI publications, such as the Sporting Code and bulletins. However, much of this seems yet to have its way into the ether. There are times when the old-fashioned ways of research must still be used. It is damned hard and slow research requiring a deal deal of time and effort. Always keep in mind that, as mentioned, little of this information was available to the interested fan many decades ago, it all had to be ferreted out, usually a piece at a time, often only collected well after the fact.
Thank you.
I optimistically hoped that such documents (the technical regulations) have been digitalized and published somewhere, but your indication is however very useful since I've never found any indication on this "yellow books" before. Now that I know that the technical regulations are included in such book I can search and purchase them.
I have no issues for sharing knowledge, it's the very nature of this forum. We all make and reply to questions. But one can't make a wide question such as this and hope to make himself a culture just by reading the replies. The best suggestion would be to provide directions where to find the answers - websites, books, libraries - and then perhaps discuss here specific issues. Does really anybody expect to see here - in this forum - published the whole regulations since motorsport began?
One second to find this:
http://en.wikipedia....One_regulations
That links describes the differences, but it is not what I'm searching since it does not report the changes in the regulations so that it is almost impossible (IMHO) to understand all the "innovations" which have been created year by year by F1 engineers to respect newer "diktat" with less performance penalties (for example the double diffuser has emerged when the regulation on the diffuser has changed to theoretically reduce the performance of the diffuser, but since the regulation do not prohibited the openings in the vertical planes joining the two references planes, it was possible for Brawn and his staff to exploit such a "grey area" which has been more completely defined in the following year technical regulations).
From my point of view in fact there are two kind of innovation in F1:
1) the innovation that appears without any technical regulation change (for example the turbocharged engine in 1977 has not been urged by any rule modification but only from the development of more advanced turbo engine)
2) the innovation that appears as an effect of a new limitation in the technical regulation (as for example the double diffuser, the brahmam bt49c hydro-pneumatic suspensions to full fill the newer requirements on minimum height in 1981).
The knowledge of the technical rules year by year should permit to understand why an innovation has appeared in a particular contest and why some technical rules has been changed over the years.
So I admit I was a bit not precise in formulating my first post and I apology for that.
