The bibliographical citations with an epigraphic/papyrological edition (to be distinguished from the master bibliography of a project or publication).http://www.tei-c.org/release/doc/tei-p5-doc/en/html/CO.html#COBI
It is generally recommended that a master bibliography, containing all works cited in a publication or project (whether including discussions or only previous publications of texts) be encoded in a separate, single file. This might validate to the EpiDoc schema or to a generic TEI bibliographic schema, or could even be a free-standing database, or a HTML page with an id for each bibliographical entry.
If encoding in TEI, the bibliography should comprise a structured list either of <bibl> elements (recommended) or <biblStruct> elements (probably overkill for most projects, but see second example below). An xml:id on each item will allow referencing or linking from the localized bibliographic citations in individual texts.
Individual texts will often contain multiple bibliographic citations, for example to works cited in commentary, the source of translations of photographs, and most importantly, to previous publications of the same text by other scholars. Within an EpiDoc edition, such citations should be contained in the <div type="bibliography">, either in an unstructured <p> (if the bibliography is a paragraph of free text with connecting prose such as, "First published in ..., from notebooks; reprinted in ...; whence ... . Later re-edited from autopsy by..." etc.) or in a <listBibl> if the citations are a simple (or numbered) list.
Each bibliographic citation may be encoded relatively simply in a <bibl> element in the form that is desired in the online (or print) edition, be that a full bibliographic reference or abbreviated author + date or similar. It is often useful, however, to link back to the entry in a bibliographic authority (generally the master bibliography), for example so that:
Assuming a master bibliography in TEI containing the entries from the first example above, the bibliographic citation below would (a) point to the Reynolds 1971 title therein, and (b) state unambiguously that the text in whose edition this citation appears was previously published as number 3 in her edition.
This would allow, firstly, the edition to display text such as ‘Reynolds 1971, 3’ or ‘Reynolds, 'Zawiet Msus' (1971), no. 3’ or similar; and secondly a bibliographic concordance to be generated that lists all of the inscriptions in each previous publication, showing which inscription in the current collection corresponds to each. (See for example the InsAph concordance for a Reynolds article.)
