So far just Vasantika Svapnam (Midsummer Night’s Dream), but this amazing website has 100’s of other valuable Sanskrit resources:
Trivandrum Sanskrit Series (Anantasayana Samskrita Granthavali) is a collection of ancient, very rare and previously unpublished Sanskrit works published by Manuscripts Library, Trivandrum in the early part of 20th century. First book in Trivandrum Sanskrit Series – “Daivam”, a work on Sanskrit grammar, was published in 1905 edited by MM T. Ganapati Sastri. Nearly 100 texts were published within a short span of 20 years and the series continues to this day.
An article on Trivandrum Sanskrit Series written by G Harihara Sastri that appeared in Indian Historical Quarterly Volume 1 in 1925 describes the genesis and growth of this series and also evaluates the unique contributions of this series to the growth of Indological studies.
