An interesting question, Darren.
I know that there is some anxiety about the possibility of putting plants under threat because of location collection data on herbarium sheets.
This is what the RBGE Site says about Herbarium Access : from
http://www.rbge.org.uk/science/herbarium/visitor-information "Visitor information
We welcome visits to the Herbarium by colleagues from recognised scientific institutes, including their students with experience in handling specimens.
To arrange a visit please contact the Curator at:

Opening hours
Daily opening hours for the Herbarium are:
Monday - Friday (excl. public holidays)

In the first instance, visitors should report to reception at 20A Inverleith Row (after 9.00am), from where they will be accompanied by a member of the Herbarium team.
Visitor policy
Because of the fragile nature of the specimens and their historical importance, visitors are required to handle the specimens with extreme care. It is expected that all visitors will have prior experience in handling herbarium specimens. They must be kept flat and carried on boards to prevent damage.
Any specimens studied need to be annotated using archival quality Determination / Fide slips, pens and glue. These can be supplied by Herbarium staff where necessary.
Any incoming specimens will be frozen on the premises for at least five days before being allowed into the Herbarium. Please allow for this if you wish to study your own material.
Specimens may be photographed for non-commercial use. Any published photographs must bear the statement ‘Published with kind permission of the Royal Botanic Garden Edinburgh'.
Please note - If you plan to visit Edinburgh during August please book accommodation well in advance as the city is extremely busy that month because of the Edinburgh International Festival. "
