In order to retain the peculiarities of the original documents such as archaic spellings, alternation between aspirated and unaspirated consonants, the use of ya btags, etc, the text is transliterated as it appears and is edited as lightly as possible with minimal annotations. As a consequence, liaisons like phyogsu (for phyogs su) and alternation between aspirated and unaspirated consonants are left untouched without emendation.
However, in order to facilitate the reading of the transliterated text, the following measures have been taken by deliberate editorial decision:
- A syllable is often divided into two parts, the first part being written at the end of a line and the second one at the beginning of the following line. In such cases, the two parts are merged together to reconstitute the original syllable and its line number is that of the line in which the radical letter of the syllable is written. For example, when sang is written at the end of line x, and the letter sa alone at the beginning of the following line (x+1), the syllable sangs is restituted at the line x.
- Very often the last letter of a syllable is written below the preceeding letter (for economy of space), like དྔ་ for དང་ , and བཀཱ་ for བཀའ་ . In such cases, dang and bka' are restituted without mention of this peculiar paleographical feature.
- Certain lines are indented in oder to clearly indicate :
- verses in six or seven syllables,
- casts of dice in divination texts, and
- evident internal divisions which however are not marked by any punctuation signs.
Full critical editing and notes can be found on the website of Old Tibetan Documents Online (OTDO), where search facilities, such as a KWIC concordance tool, are also available. Furtheremore, as updating, revision, and enlargement will continually and regularly be done on the website, readers are advised to refer to it for the latest version.
The transliteration system of Tibetan followed in this edition is based on the Wylie system, but some changes and additions have been made in order to faithfully transliterate certain features which are peculiar to Old Tibetan manuscripts.
Vowelsཨ་ ^a ཨི་ ^i ཨྀ་ ^I ཨུ་ ^u ཨེ་ ^e ཨོ་ ^o
ཨཻ་ ^ai ཨཽ་ ^au ཨོེ་ ^oe
- The letter ཨ is transliterated as ^a with ^ as consonantal element.
- The reversed gi-gu is transliterated with I (capital letter).
གྀ་ gI ནྀ་ nI

གཡག་ g.yag ~ (cf. གྱག་ gyag) གཡུང་ g.yung ~ (cf. གྱུང་ gyung)
- The wa-zur is transliterated with v, not with w.
གྲྭ་ grva ཕྱྭ་ phyva

ཨཱ་ ^'a ~ (not â) ཧཱུ་ h'u ~ (not hû) སཱོ་ s'o
- When two consonants form a vertical ligature which is not legal in classical Tibetan grammar, the + sign is inserted between them.

- The anusvāra is transliterated with M (capital letter).
ཨོཾ་ ^oM ཨཱོཾ་ ^'oM

- A sign marking the beginning of a follio, paragaph, etc. is, irrespective of its forms, transliterated with \$.
