Cloud-based library systems

Trzecia Strona Sp. z o.o. commenced business activity in 2015, successively developing its portfolio of IT solutions for libraries. The first solution it offered was hosting of library systems. A year later we launched our Metrao widget on the largest website for readers in Poland – lubimyczytac.pl – which presents the collections of a third of all public libraries in the country. Tens of thousands of readers use it every day. In 2017, under an agreement signed with Librus, we started working on a library system for schools: e-biblio. It was first implemented in March 2018; since then, the system has been implemented in over 1,600 schools in Poland so far. In 2019, we expanded our library systems offering to include systems dedicated to scientific, academic and pedagogical libraries: Alfios and Bibliografia.
