question / pregunta:
I would like to view several of the separate documentaries that make up the series, Our Secret Century. However, I can't find these documentaries anywhere, for purchase or on the Prelinger archive (the archive has great individual ephemeral videos, but not the 80 minute titles like The Rainbow is Yours). Is there somewhere I could go to buy, rent, or access these wonderful videos?
Documentary Availability
I would suggest trying to use interlibrary loan through your public library or another library you have privileges at. There are a handful of libraries that own these materials (it was produced on CD-ROM), but unfortunately none are in your area. So I believe your best bet would be to see if your library can borrow them for you from one of the institutions listed here: http://www.worldcat.org/oclc/224097768 . This is the record for the most complete collection that is the 10 documentaries that in the series. However, there are separate listings for sets of two of the documentaries if there are some you are looking for some in particular.
You may also be able to buy these CD-ROMs individually off of both Amazon and Ebay from private sellers. (On Amazon the CD-ROMs seem to be listed in the Books section which is rather confusing, but they appear to be the correct item just inconsistently entered into the database by private sellers.)

I hope this helps and you are able to track down these documentaries!
Our Secret Century
I still have copies of vols. 1-8. I'd be happy to send them to you if you cover postage costs. You may have a difficult time recreating the menus and interactive elements on current computer systems, but the films and all the collateral material are QuickTime movies, so if you poke around the disc directories you should be able to play at least the ingredients.
