As part of a pilot project to make the museum accessible for everyone, the authorities are working with Blind Persons' Association in the city to install Braille sign boards.
"We will have signages in all the galleries within a year. It doesn't matter whether you can see with your eyes or not. What we have here is national treasure and it should be accessible for all," museum Director Dr Jayanta Sengupta told PTI.
The first one to have such signage will be Bharhut gallery which shows the architectural remains from Bharhut belonging to Shunga period, along with similar fragments from Bodhgaya during second and third century BC.
Buddhist stupa is the most precious possession in the gallery.

Amiyo Kumar Biswas of the Blind Persons' Association said they prepared Braille text for signage in three languages - Hindi, English and Bengali.
The 202-year-old Indian Museum, the oldest in Asia,
already has a modelling unit comprising five staff who make different types of models using clay, plaster of Paris, fiber glass, etc.
Biswas, himself a visually challenged person, said they visit museums but take someone along with them who can describe the collection to them verbally and read out the signages.
"If the museum has replicas which are not locked under glass doors then we will be able to feel it on our own to find out how the original might look like," he said.
"We have guides and we also have trained our interns to act as guides," they said.
On the occasion of World Environment Day which falls on June 5 each year, the Braille gallery will be inaugurated.
