Until last month's earthquake, the Kaiser Library buzzed with Nepali students, intellectuals and tourists attracted by its collection of rare books, maps and ancient manuscripts -- all housed in an opulent former palace.
Now wooden bookcases lie smashed on the floor of the 120-year-old building, which was gifted to the nation by the Rana dynasty that ruled Nepal for more than a century before losing power in 1951.
The library was closed on April 25 when the quake struck, and Karmacharya said it was two days before she plucked up the courage to go and see the destruction.
"I cried when I got came back home, I couldn't help myself. The books are like my children, and I love them very much.
"Thank God it was a Saturday and there were no readers inside."
Karmacharya estimates that the quake damaged around a third of the 28,000 books in the Kaiser Library.
They were the collection of Kaiser Shumsher, a scion of the Rana family who travelled to England in 1908 and fell in love with the grand houses and their private libraries.
Inside the building, antique statues lie in pieces on the floor and stuffed animal heads and portraits of Nepal's former rulers in full military dress hang precariously on severely cracked walls.
In one room are the fragments of a suit of armour smashed to pieces in the quake; in another, a stuffed Bengal tiger and a huge bearskin rug, the head and paws still attached.
Books in the English section -- many of which Shumsher brought back from his visit to England -- include John Buchan's adventure classics and such titles as "The Big Game of Asia".
It also houses rare South Asian manuscripts on Buddhism, Tantrism and astrology, some so old they are written on palm-leaves.
