En undersökning av Libra IIIs OPAC utifrån två perspektiv
This master thesis is an attempt to study the interface in itself, where the human meets the machine and the problems that can arise. I study a particular interface, namely the OPAC of Libra III. In 1999 IFLA presented recommendations for what an OPAC shall contain, and in one part of my master thesis I compare Libra III with these recommendations from my opinion. In another part of my master thesis I make an investigation where I let five by me chosen persons answer some questions from me, both by doing and verbally. I draw the conclusion that Libra III follows most of the recommendations of IFLA in a sufficient way. There are deficiencies in how plain you can see what is happening in the system when your search for example doesn't give any hits. Really important the simplicity seems to be to make a search successful, and this IFLA recommends at the same time as my subjects of the experiment look for it. From my point of view failures depend on a combination of the fact that the constructors of the system haven't taken enough consideration to the end-users of the system and that the education of the users hasn't been good enough. Taken altogether my judgement of Libra III after all is that it is a good system both seen from IFLA and from my subjects of the experiment, but that this is a field where more can be done.
