+# 🏢 ZygAI – Lintel Info ‘98: Lithuanian Companies Dataset (ABC)
+
+**ZygAI Lintel ‘98 Companies** is a fully digitized, structured dataset based on the Lithuanian business information catalog *“Lintel Info ‘98 – Įmonių anketiniai duomenys”*.  
+Originally published in 1998, this dataset preserves and structures detailed records of Lithuanian IT, technology, and service companies that operated during the early post-Soviet economic period.
+
+---
+
+## 📘 Overview
+
+This dataset contains structured information extracted from the *Lintel Info ‘98* printed volume — one of the first Lithuanian-wide business catalogs after the country’s independence.  
+Each record represents a company with contact, activity, and management details, providing a snapshot of Lithuania’s corporate and technological ecosystem in the late 1990s.
+
+The dataset was manually digitized, cleaned, validated, and merged as part of the **ZygAI Research** archival initiative.
