Nyingma Gyubum
Nyingma Gyubum (, Collected Teachings of the Ancients) is a collection of Vajrayana texts reflecting the teachings of the Nyingma ("Ancient") school of Tibetan Buddhism. The contents of this collection comprises the Inner Tantras common to the Nyingma: the Mahayoga, Anuyoga, and Atiyoga (Dzogchen) tantras. An important facet of Bhutanese culture, studying the Nyingma Gyubum is considered honorable. Canonization
Nyingma Gyubum texts are generally excluded from the Kangyur and Tengyur sections of the Tibetan canon by the Sarma (New Translation) traditions (Sakya, Kagyu, Gelug). It is theorized that the formation of the first edition of the Nyingma Gyubum began in the twelfth century, with certain texts drawn from the Terma literature. There are only seven extant texts of the Space Class of Dzogchen, each of which is contained in the Nyingma Gyubum. Extant versions
Cantwell and Mayer have, since 1996, published four monographs on the rNying ma'i rGyud 'bum, and have critically edited a number of its texts. Their work has established that the nine easily available extant versions fall into three distinct lines of descent. Thus, the four Bhutanese versions of Tshamdrag, Gangteng-A and -B, and Drametse form one line of descent, all from a Lhalung original. The Rigzin, Tingkye, Kathmandu and Nubri versions all hail from a common ancestor in South Central Tibet, but Kathmandu and Nubri are of a slightly different sub-branch to the Tingkye and Rigzin. Dege is unique in itself. Harunaga & Almogi (July 2009) hold that there are, at minimum, seven extant versions of the Nyingma Gyubum of different sizes, ranging from 26 to 46 volumes in length. Degé (Wylie: sde dge) Edition
The terton Ratna Lingpa (1403–1471) was important in the compilation of the Nyingma Gyubum's first evocation and Jigmed Lingpa (1729–1798) built upon this compilation and it was published with the impetus of Getse Mahapandita  (1761–1829), one of Jigme Lingpa's disciples, through patronage of the royal house of Degé. Further to this, Rigpa Shedra (2009) hold that the Nyingma Gyubum:
"...was first compiled by the great tertön Ratna Lingpa after similar compilations of texts made in the 14th century, such as the Kangyur and the Tengyur, had omitted many of the Nyingma tantras. It was first published towards the end of the 18th century under the guidance of the Omniscient Jigmed Lingpa, in Derge, thanks to the patronage of the regent queen Tsewang Lhamo." Jigme Lingpa gathered Nyingma texts that had become rare, starting with Nyingma tantras held in the manuscript collection of the Mindrolling Monastery. This collection of the Nyingma tantras led to the amassing of the 'Collection of Nyingma Tantras', the Nyingma Gyübum (Wylie: rNying-ma rgyud-'bum) for which Getse Mahapandita wrote the catalogue, proofread and arranged for its printing by soliciting the expensive and labour-intensive project of carving the wood blocks for the block printing. The wood block carving was forded through the patronage of the 'Degé' (Wylie: sDe-dge) Royal Family of Kham who favoured and honoured Jigme Lingpa. Getse Mahapandita proof read the Nyingma Gyübum.

Tingkyé (Wylie: gting skyes) Edition
In late last century, Dil mgo mkhyen brtse rin po che (顶果钦哲仁波切) (1910–1991) discover more manuscripts in Bhutan, 46 boxes in Mtshams brag monastery (禅扎寺) and 36 boxes in Gting skyes monastery (定切寺). This version is more complete. The texts were published by The National Library of Bhutan (不丹皇家政府国家图书馆) in 1982. An admirable pioneering catalogue of this collection, including all titles, chapters and colophons, was made by Kaneko in Japan. Some years later, this was usefully rendered into a digital version by THDL. Tsamdrak (Wylie: mtshams brag) Edition
Catalog of The Collected Tantras of the Ancients, Tsamdrak Edition @ THL Tibetan Literary Encyclopedia
Anthony Hanson-Barber provided the first title and colophons catalog of this collection. His work was then expanded into a fuller catalog including chapter headings by the THDL team. Importantly, the Kunjed Gyalpo is the first text in the Tsamdrak edition of the Nyingma Gyubum. Catalog of the Master Edition
Though not a true extant edition, the THL Tibetan Literary Encyclopedia under the directive of Germano has distilled a Master Edition taking the above mentioned editions into account. Catalog of the Master Edition of the Nyingma Gyubum @ THL Tibetan Literary Encyclopedia

What constitutes a tantra according to the Nyingma? Early in the naturalization and acclimatization of Indian and Chinese tantric Buddhadharma and siddha traditions into the Himalaya and Greater Tibet in general, the Guhyagarbha Tantra () of the Mahayoga class of literature "represents the most normative vision of what constitutes a tantra for these Nyingma lineages". Indigenous Tibetan exegetical works discuss what constitutes a 'tantra' in an enumeration of ten or eleven "practical principles of tantra" () understood as defining the distinctive features of mainstream tantric systems as understood and envisioned at that point in time:
'A view of the real' ()
'determinate conduct' ()
'mandala array' ()
'successive gradation of empowerment' ()
'commitment which is not transgressed' ()
'enlightened activity which is displayed' ()
'fulfillment of aspiration' ()
'offerings which brings the goal to fruition' ()
'unwavering contemplation' (), and
'mantra recitation' () accompanied by 'the seal which binds the practitioner to realization' (). Modern 'Western' discourse in English: an etic narrative

Timeline of salient scholarship
Germano (1992) discussed the Atiyoga tantras in his thesis. Ehrhard (1995) documents the discovery of manuscripts of the Nyingma Gyubum from Nepal. In 1996 at the University of Leiden, Mayer completed the first PhD that was specifically on the rNying ma'i rGyud 'bum and its different editions. In his thesis he established for the first time the various branches of transmission of the rNying ma'i rGyud 'bum by stemmatic analysis. These three branches he identified as the East Tibetan, the Bhutanese, and the South Central Tibetan (which subdivides into two sub-branches). This remains the standard method to categorise the various  rNying ma'i rGyud 'bum  editions, since all editions subsequently discovered have been found to  fall within one or another of these lines of transmission. Mayer's PhD also identified the first irrefutable proof of the sources of Mahāyoga texts, and reviewed what was then known of the rNying ma'i rGyud 'bum's history. Germano's earlier work was further appended with Germano (2000) specifically related to the Nyingma Gyubum. Cantwell, Mayer and Fischer (2002) in association with the British Library documented the Rig 'dzin Tshe dbang nor bu Edition of the Nyingma Gyubum. Cantwell and Mayer subsequently published their third monograph on the rNying ma'i rGyud 'bum, discussing its history and its various editions and providing critical editions of two sample texts: "The Kīlaya Nirvāṇa Tantra and the Vajra Wrath Tantra: Two Texts from the Ancient Tantra Collection". Vienna, 2006. Derbac (2007) tendered an MA thesis on the Nyingma Gyubum as a whole. In 2008, Mayer and Cantwell published their fourth monograph relating to the rNying ma'i rGyud 'bum, in which they showed that virtually all Dunhuang text on Phur pa subsequently reappeared within various parts of the rNying ma'i rGyud 'bum, thus proving that the rNying ma tantric materials are definitely contemporaneous with or older than the Dunhuang texts. As of 2010, they are still at Oxford University and completing their fifth volume on the rNying ma'i rGyud 'bum. As well as the monographs, they have also produced catalogues and many journal articles and conference papers on the rNying ma'i rGyud 'bum. Etic discourse and narrative
In his MA thesis for the University of Alberta, in the terrain of scholarly etic discourse of the manifold Nyingma Gyubum editions, Derbac (2007: p. 2) proffers:
"...that the major editors of the various rNying ma'i rgyud 'bum editions played a far greater role in emending colophons, catalogues, and editions than scholars have previously assumed." In saying this, Derbac is agreeing on the one hand with emic [traditional] scholarship, which frankly celebrates the major role of the famous editors such as Ratna Lingpa and Jigme Lingpa in compiling catalogues for the rNying ma'i rgyud 'bum. In addition, he is also confirming the conclusions of earlier scholarship, such as [1] Mayer's Leiden PhD thesis of 1996, which was later published as a book 'The Phur pa bcu gnyis: A Scripture from the Ancient Tantra Collection' [2] the conclusions of David Germano's THDL collection in the early 2000s, and [3] Cantwell and Mayer's book 'The Kīlaya Nirvāṇa Tantra and the Vajra Wrath Tantra: Two texts from the Ancient Tantra Collection', published in 2006 by the Österreichische Akademie der Wissenschaften, Vienna. Derbac cites all the above three sources, as well as others of the works by Mayer and Cantwell on the rNying ma'i rGyud 'bum. Primary resources
