There is only one set of files and most href's include "target" specifications. If you are running a browser with frames support and do not select "frames", different files will be placed in different browser windows. There also seems to be some frame implementation variations.
For some time the working group name from the IETF email announcements have been used as a keyword. As a result the keyword organization of RFCs will include lists of RFCs done by working group.
Misc. other RFCs of possible interest: "Not All RFCs are Standards" 1796, "Architectural Principles of the Internet" 1958, and "Guide for Internet Standards Writers" 2360.
The draft and proposed standards list include age of RFCs in months (with months >24 displayed in bold). Standards and Protocols documented by obsoleted RFC have number displayed in bold. Protocol names that match port protocol have the port number listed.
Author, Date, and Term indexes have RFCs documenting standards displayed in bold.
email addresses are extracted from RFC editor announcements and included in the Author index. Authors (typically organizations) that are also listed as terms, have their associated RFCs listed as such in the term index.
There has been quite a bit of data cleaning, especially with respect to updates/obsoletes and author names. In the RFC index entries, the author order is not preserved when loading into the database. When re-creating the author list for a RFC, it is built in alphabetical order.
There are a couple instances where Obsoletes/Updates may not be listed:
RFC text files are now being scanned for References section and the information extracted and presented in manner similar to Updates/UpdatedBy. Also, RFCs that mutually reference each other have the References relationship converted to symmetric "SeeAlso". For more detail, see detailed discussion
The IETF draft origin of an RFC will be listed for the first six months after it has been made an RFC.
For more complete description see "The Internet Standards Process" BCP-9 and the latest rfcxx00.txt.
Information that used to appear STD-1 section 6.10 (misc. examples 2000, 2200, 2300, 2400). Only obsoleted standards listed in rfcxx00.txt are listed (standards that were published since and then obsoleted are not listed).
20th Anniversary Of The Internet!, also #1, #2, #3. also RFCs: 801 and 832, 833, 834, 835, 836, 837, 838, 839, 842, 843, 845, 846, 847, 848, 876
