To view an apparatus, please choose one from the Select Apparatus box above. An overtext will then load, from which the entry for a particular chapter and verse may be selected from further drop-down menus. The sigla of the witnesses are linked to the corresponding verse in the transcription files. Clicking on a siglum will open the full transcription in a separate window.

Where a manuscript has been corrected, the first-hand reading is indicated by the addition of a * following the siglum. The corrector's reading is indicated by the suffix C. Where different correctors have been identified, they may be indicated by alternative suffixes, such as C1 or C2. A first-hand correction is indicated by C*. The addition of S to the siglum indicates that this is a supplement, copied at a different time to the rest of the manuscript.

The apparatus for the majuscule edition corresponds to that of the printed edition (2007). The transcriptions to which it links, however, have been updated as part of further work on the ECM. The Vetus Latina synopsis corresponds to the latest version of the transcriptions presented on this website. The apparatus and linked transcriptions for the Byzantine edition (2007) and the Family 1 edition (2013) are in self-contained sites, in order to correspond to the editions at the time of their publication: in the case of these two editions, there may be some display issues with browsers other than Firefox.

To view a transcription, please select one from the relevant drop-down menus above. This will load an HTML version which is optimised for viewing in a web-browser. A link to the corresponding XML file is provided in the header. The transcription header also gives information about the manuscript (where this is provided in the transcription), which may include links to the online version of the Kurzgefasste Liste and the Trismegistos catalogue (Leuven Database of Ancient Books). A drop-down menu allows users to navigate to a specific page of the manuscript, while entering chapter and verse numbers in the free-text entry boxes and clicking 'Go' will take users to the corresponding verse of John (if it is present in that transcription).

Further details about items in the transcription are provided by means of hover-over boxes, which appear when the cursor is placed on the relevant text. Verse numbers and line numbers in grey have been added for the purposes of the edition. In addition, the following conventions are observed in the transcriptions:

• Readable text is presented in black.
• Unclear text is presented in grey with a dotted underline.
• Supplied text is presented in red with square brackets. Where text has not been supplied to fill the missing portion, the size may be indicated as the approximate number of missing characters (e.g. 5), or by ... to indicate a whole line or more. (More detailed information may be supplied in the XML file.) If it has been noted that the text is supplied in a lacuna, where the parchment is not longer present, this is shown by a white background.
• Paratextual numbers (e.g. chapter numbers, Ammonian sections) are presented in purple.
• Material present in margins is indicated by raised brackets and a hover-over box.
• Corrections: by default, the reading of the original copyist is shown. Where this has been corrected, the original reading is coloured blue: placing the cursor in this text will reveal a hover-over box with details of the different reading(s) and the hands responsible for them.
• Abbreviations: nomina sacra are not expanded, and are marked with an overline. Other abbreviations are normally expanded using parentheses.
• Editorial notes are indicated by ℹ; the contents of these appears in a hover-over box.
