# 📚 Institutional Books Topic Classifier

This model was trained as part of the analysis and post-processing work performed in preparation for the release of the [Institutional Books 1.0 dataset](https://huggingface.co/collections/instdin/institutional-books-68366258bfb38364238477cf) by the Institutional Data Initiative.

We used this text classifier to assign a topic, derived from the first level of the [Library of Congress' Classification Outline](https://www.loc.gov/catdir/cpso/lcco/), to individual volumes.

Complete experimental setup and results are available in our [technical report](https://arxiv.org/abs/2506.08300) (Section 4.5).
