The National Library of Venezuela offers one of the most unique experiences in online library catalogs. To be able to check the catalog, you need to go first on a part of their website where you have the instructions on how to use it, only in spanish for now, but take my word on them.
First you will need a software to uncompress files, like Winizip or Winrar, then you have to download a “3270 emulator” for Windows, sorry, no Linux or Mac OS support for now, but works on Vista and 7, so that alone it’s pretty cool. As for this 3270 emulator, Wikipedia says it’s “a computer program that duplicates the functions of an IBM 3270 (manufactured c.a. 1972) mainframe computer terminal on a PC or similar microcomputer.”
So, following the installation of the emulator, configure the IP to 126.96.36.199 and you will enter the automation suite ND-NOTIS. Again, taken from Wikipedia: “ND-NOTIS was a tightly integrated yet modular office automation suite by Norsk Data introduced in the early 80s, running on the SINTRAN III platform on both ND-100 and ND-500 architectures.”
Now there’s no more mouse input for you, so you have to login and input commands using only the keyboard: you press “b”, then “Enter”, then “Tab”, you put in the username “OPERATOR” and password “OP3RAT0R” (pretty sneaky, huh?), then “Enter”, “F10” and write in caps the word “LUIN” and… VOILA!
