Thank you much for this information, as some of you may have gathered the reason for my request of this information was for the following thread that I started http://www.originaltrilogy.com/forum/messageview.cfm?catid=2&threadid=2552
Unfortunatly, this changes some of my assumptions made, so based on the information present in the copyright listing for Star Wars and the dates the LoC aquired their copies if the crawl was already made and could have been present in the 1977 version than its possible that the versions that the LoC recieved in '78 & '79 include this crawl...the two things that makes this seem unlikely however is that the copyright date is may 25 1977, and when the subtitles for the hearing impaired were added this was noted in the copyright so it would make sense that the addition of information to the crawl would also have been noted. Also, the fact that the rereleases of Star Wars were all without the Episode IV until 1981 and the copies the LOC recieved were before this date.
What is also strange is that the earliest copy that the LOC has is dated as being aquired about a year after the movie came out. Now there is the fact that the online copyright database only contains works registered on or after 1/1/1978, but i dont think that would keep an aquisition of the film reels in 1977 from appearing on the information I refer to in the other thread.
I was giving a few more sources I can check, so hopefully I can unquestionably establish what version the print the LOC has on file is.
