If the guide is not available just DM me one or two days before you arrive. Any BSC staff can give a tour to a small group. But it is necessary to schedule ahead and avoid events/other tours.
You can also visit the luminous click on Via Laietana. It is old, free (on the sidewalk), but interesting.
You can enter any library to browse. Abello library in Les Corts hosts the Asimov Foundation collection. I think the Sagrada Familia library has the scientific illustration collection, etc.
I remember seeing a really old elevator in the Gòtic neighborhood... I can't remember the name of the museum where it was but it was at the museum entrance (you can just walk in and have a look).
You can also walk in most campi like UPC, UB, etc. They have some exhibitions and also panels with history of the uni and faculties. As well as libraries too.
