Popular Library On the other side of the tree, Community reading center in Parque Saavedra, La Plata, Argentina.

The Biblioteca Popular Del otro lado del árbol occupies a repurposed container in Parque Saavedra, at Calle 14 between 66 and 67, opposite the Sor María Ludovica children's hospital in La Plata. More than a hundred volunteers fitted out and painted the container inside and out with drawings. Its collection holds over 22,000 books of children's and young adult literature, plus a bebeteca, a Braille section and a Museum of the Book with pre-1980 titles.

In February 2011 Paula Kriscautzky proposed to her family a library in a disused shed in Parque Saavedra, facing the Hospital de Niños Sor María Ludovica, as a waiting room and neighbourhood reading room. Over a hundred volunteers fitted out and painted a container on land ceded by the Municipality of La Plata. It opened on 2 April 2011, Pilar Andicoechea's birthday, with 2,000 new books brought by 2,000 people. A May 2020 fire damaged the collection and premises, rebuilt with support from the La Plata community.

The name comes from Mandana Sadat's picture book "Del otro lado del árbol", a favourite of Pilar Andicoechea; Paula Kriscautzky chose it because the shed's surroundings resembled Sadat's illustrations. Books can be taken outside to read under the park trees, and no fines are charged for late returns. Workshops with families, oral storytellers, concerts and talks run alongside the collection.

The library is located on Calle 14 between streets 66 and 67, making it accessible on foot from several parts of the neighborhood. Annual membership provides access to the book collection and participation in workshops and activities throughout the year.

This library inspired and sparked the creation of similar facilities in other cities such as Olavarría and San Carlos de Bolívar across the province. The ripple effect demonstrates how a single community project became a model that other towns chose to replicate.
