By “Girnar evidence books” you are most likely looking for Jain granths that give scriptural / historical pramāṇ (evidence) for Girnar’s importance, especially as Bhagwān Nemināth’s moksha‑bhūmi.

Here are some main Jain texts and books often used as “evidence” for Girnar:

1. Kalpa Sūtra (Śvetāmbara āgama)

- Mentions the life of Tirthankars and includes reference to Nemināth Bhagwān and Girnar (Raivatgiri / Raivatachal) as his kalyāṇak‑bhūmi. - Used especially in Śvetāmbara tradition as scriptural pramāṇ.

1. Uttarādhyayana Sūtra

- Also a Śvetāmbara canon text. - Contains episodes connected with Nemināth and his renunciation, traditionally linked with Girnar.

1. Nirvāṇa Kāṇḍ (Digambar tradition)

- Prākrit granth describing nirvāṇa‑sthal of Tirthankars. - Lists places like Girnar among the siddha‑kṣetras where Tirthankars attained moksha.

1. Tīrtha‑kalpa / Vividhatīrtha‑kalpa‑type texts

- Medieval Jain tirtha‑māhātmya granths. - Give detailed mahimā and itihās of Girnar as a major Jain tīrth.

1. Modern historical / compilation books (good for study evidence)

- “Shri Girnar Tirthno Itihas” – detailed history of Girnar tīrth, temples, inscriptions, Ashokan edicts, renovations etc. - “Girnar Granthonni Godmā” – compilation of many old Jain references glorifying Girnar, almost like a “document file” of scriptural quotations. - Various “Jain Tirtho no Itihas” / “Tirth Darshan” type books (both Digambar and Śvetāmbara) have a separate chapter on Girnar with references to older granths.
