Dear Christophe,

Thank you very much for finding all this additional bibliographic information. Very interesting (and inspiring) about the Scheut Memorial Library that you provided a link to. Thank you also for attaching a scan of Rahder's article from Acta Orientalia giving the seventh bhūmi and its commentary by Vasubandhu (I seem to have misplaced my photocopy of it from his thesis).

While on this topic, it may be worthwhile to note that Rahder's edition of the Daśabhūmikasūtra was based on seven paper manuscripts. Kondo's edition was based on eight paper manuscripts, four of which are different from the ones used by Rahder. The two very old manuscripts reproduced by Matsuda Kazunobu indicate the need for a new Sanskrit edition of this text (Two Sanskrit Manuscripts of the Daśabhūmikasūtra, Preserved at The National Archives, Kathmandu. Bibliotheca Codicum Asiaticorum, 10. Tokyo: The Centre for East Asian Cultural Studies for Unesco, The Toyo Bunko, 1996). Interestingly, as Matsuda points out, neither of these two have the verses, gāthās.

On the English translations, besides the one made by Megumu Honda that Potter referred to in the quotation you gave from him (I have a scan of this ready at hand if anyone needs it), and the two new ones made from the Chinese by Bhikshu Dharmamitra that I referred to, there is one included in Thomas Cleary's complete translation of the Avataṃsaka-sūtra from Śikṣānanda's Chinese published as The Flower Ornament Scripture: A Translation of the Avatamsaka Sutra, 3 vols., 1984-1987 (1-vol. edition, 1993), as chapter 26. However, Bhikshu Dharmamitra points out in his Translator's Introduction (p. 22) to his translation of the Daśabhūmika-sūtra from Śikṣānanda's Chinese translation of the Avataṃsaka-sūtra, chapter 26, that Cleary's translation

"appears to instead be a loose translation of the P. L. Vaidya Sanskrit edition of the Daśabhūmika Sūtra. Hence his supposed translation of this chapter has little if any relation to Śikṣānanda's Chinese edition."

It may be noted that Bhikshu Dharmamitra has included the Vaidya edition of the Sanskrit in Roman transliteration (from the Digital Sanskrit Buddhist Canon Project) at the back of both of his translations of the Daśabhūmika-sūtra from the Chinese. He has correlated this to his translations by adding to them the alphabetical section headings (A, B, C, etc.) from the Vaidya Sanskrit edition, which originated with the Rahder edition. Vaidya's edition is based on Rahder's edition (see Vaidya's Introduction, p. 1). It is not exactly a "revised" edition, as Potter loosely termed it, since Vaidya did not have any additional materials from which to revise it. He apparently did not have access to Kondo's edition.

Dear David,

For clarification, I add here the University of Louvain (KU Leuven) reference to an exemplar of Rahder's 1926 Ph.Thesis (the exemplar is located in the rich "Scheut Memorial Library", in the name of the East-Asia missionary congregation: https://www.kuleuven.be/verbiest/sml)

Creation Date
1926.
Publisher
Leuven : Istas,
Coverage
p. 213-256: Dasabhumika-Sutram, seventh stage
Format
XXVIII, 99, 216-256, 28 p.
Description
Dissertation note : 
Acad. proefschrift doctor in de Lett. en Wijsbeg. Rijksuniv. Utrecht


So as noted in the reference from the "Dutch Studies in South Asia, Tibet and classical Southeast Asia" web-page (quoted below), the printing of the thesis was in Louvain with the same printer J. Istas. It is in fact nearly the same exemplar as the SBÉO (Geuthner) published one, except the cover and the additional pages "216-256" corresponding to the "second part" issued in Acta Orientalia 4, 1926, pp. 214-56 [there would exist a reprint of the latter in "SPJP [? not in the abbr. table] 581-623" according to Potter BIPh 81.1.3]; I attach here a scan of the AO publication.

After a quick checking, the pages published in Le Muséon (then also printed by J. Istas, later managed by Peeters Publ.) 39, 1926, p. 125-252, correspond exactly to the part 1 (and only this first one) of the printed thesis and the book. In fact there was a double pagination in Le Muséon for this article, also paged 1-128.
Muséon pp. 125-152/1-28 = Book pp. I-XXVIII 
153-252/29-128 = 1-[100]
(so the Appendice, pp. 1-28 is not in Le Muséon)

There is a review of Rahder's thesis by C. A. F. Rhys Davids in The Journal of the Royal Asiatic Society of Great Britain and Ireland no. 1 (Jan., 1927), pp. 160-162.

K. Potter in EIPh t. 8, 1999 (Buddhist Philosophy from 100 to 350 AD) p. 738 fn. 271, adds that "this work is available in Sanskrit and edited by Ryuko Kondo (Tokyo 1936; Kyoto 1983). An older edition by Johannes Rahder (Le Muséon 39, 1926, 125-252) is available as revised by P.L. Vaidya (Buddhist Sanskrit Texts 7, Darbhanga 1967). It has been translated into English (including the quotations in our summary) by Megumu Honda in "Annotated translation of the Daśabhūmika Sūtra (revised by Johannes Rahder)" in D. Sinor (ed.), Studies in South, East and Central Asia (presented to Prof. Raghu Vira) (New Delhi 1966), 115-276. — see also for these references, BIPh 81.1.

For completing Rahder's bibliography on the Dutch Studies page, for the references:

• 1931 - “The gāthās of the Daśabhūmika Sūtra (Gatha Portion).” The Eastern Buddhist (?).

It was a joint publication with Shinryu Susa, issued in two parts in the journal The Eastern Buddhist (Kyoto: Eastern Buddhist Society): pp. 335-359 for the [Part I]. The second part 'The gāthās of the Daśabhūmika-Sūtra (concluded)" was in The Eastern Buddhist VI, 1 ( April 1932) pp. 51-84. For viewing the two parts together (as the offprint was): https://pdfslide.net/documents/dasabhumika-sutra-1931-32-gathas.html or https://fr.scribd.com/doc/225404930/Dasabhumika-Sutra-1931-32-Gathas 


• 1928 - Glossary of the Sanskrit, Tibetan, Mongolian and Chinese versions of the Daśabhūmika-sūtra, Paris (Buddhica: Documents et travaux pour l’étude du Bouddhisme 2,1).

But of course all these texts are made available on your website (as I saw after writing)!
