Hi Fosbeck
Yes, the record Office gets very busy, and it is essential to book.
I arrived there a couple of weeks ago to find no seats available, so after more than 1 hour waiting for a possible seat, I left and went and did other things.
Yes, you can book mico fiche / film reader, computer terminal for your laptop or just a seat at the research tables.
I usually book for all day, but only use the paper records and type them in my computer - so not sure about use of the film / fiche readers.
You could ring and book one for the morning session, then ring a bit later and book one for afternoon session if its not possible to book all day - but dont leave it till the last minute to book.
Hope that helps
