Radhika Menon has been working since 1996 to bring local stories and fiction to children in multiple languages across India.
Indian children now have access to literature in English, Hindi, Tamil, Telegu, Malayalam, Bengali, Kannada, Marathi and Gujarati languages thanks to her publishing house.
But fewer than 17% of profiles on Wikipedia are of women
So you are invited to create or expand articles about women on the site today
More than 400 profiles have been added or edited so far
People are joining in at events in Istanbul, Cairo, Dhaka, Jerusalem, Delhi, Abuja, London, Cardiff and more. But if you're inspired, you can do this from home.
Let us know who you're adding using #100womenwiki or email us at bbc100.women@bbc.co.uk.

Dancer & activist: 'Dance is a political act'
Shakil Adil/APCopyright: Shakil Adil/AP
Sheema Kirmani is a classical dancer, performer and social activist. She describes herself as a feminist and Marxist.
She says “Dance is a means of communication and a political act”.
She founded Tehrik-e-Niswan (The Women’s Movement) in Pakistan to raise awareness about the plight of women.
Bahia Shehab was made famous during the Egyptian revolution in 2011, when former President Hosni Mubarak was forced to resign. She painted the word 'no' across the streets of Cairo.
She has gone on to spread her message of using art as a form of protest across the world.
That has changed, and here is the new profile. Ione Wells, who nominated her and wrote the page, said: "She is a real example of someone who can channel anger into a positive art form."

Male Wikipedia editor's account suspended in Turkey
There have been a lot of positive reactions to our 100 Women edit-a-thon. But some BBC teams have also faced resistance and abuse from those who don't agree with the women being added.
BBC Turkish reporter Rengin Arslan tells us what happened after nine profiles were added to Wikipedia Turkish. After the team did a Facebook Live about the entries, more and more people heard about the event, she says. It wasn't long before a male Wikipedia editor got in touch.
"He complained about each of our entries by saying they are not 'notable' despite the fact that some others appeared in other languages before Turkish," says Rengin.
"Wikipedia's Turkey team helped us to sort out this problem and he was suspended of being an editor for six months."
She said one of the BBC's guests was also "harassed by a terrible image sent to her Wiki account message box". But as she was a woman journalist, she said, "This was not the first time".
"At the end of the day I am delighted to see there is a discussion on the Wikipedia Turkish page about what we have done," says Rengin.
Civil rights activist in 'legendary' protest photo added
The woman whose picture at a Black Lives Matter protest was hailed as "legendary" is now included in Wikipedia.
Ieshia Evans was photographed calmly standing in front of two heavily body-armoured police officers in Baton Rouge, Louisiana, in July, at a protest after a man called Alton Sterling was shot dead.
She was nominated by Janice Molyneux, who said: "When I found out only 17 percent of women were on Wikipedia I was shocked. I wanted to do something positive to redress the balance."
Ah, the Rio Summer Games. Such a blur of excitement.
It seems that after the blur, some key lines are missing from the Wikipedia record.
Take Amy Marren. She won bronze for Team GB in Paralympic swimming, but the medal wasn't mentioned on her profile on the online encyclopaedia.
Until now.
And who set the record straight? Her teammate, Susie Rodgers, being a good egg. Here's the amplified page.

The first edit-a-thon entry today for a Great British Bake Off contestant?

1 transgender male
That compares to less than 17% worldwide.
British birth control advocate added
