Compare intentional verse lines with screen wrapping, checking stanza spacing, indentation and quotation provenance.

English translation of the [Chinese original](<https://allluckly.cn/guides/nasbook-epub-poetry-linebreaks/>), translated on 2026-10-27. Original publication dates, attribution, code and version notes are retained.

Line breaks can be part of a poem, so smooth prose reading is not enough. Use an authorised poetry EPUB with a known edition to compare verse lines, stanza gaps and indentation across display widths. Added screen wrapping is not a new authored line; begin with a trustworthy reference.

## Establish the poem and edition

Choose a moderate poem with at least two stanzas and one long line. Record author, title, edition and translator where relevant, using a reliable reference. Mark first line, longest line and stanza boundary rather than combining unrelated online layouts into a supposed standard.

## Read the complete poem after import

After importing, verify title, attribution and complete boundaries before changing layout. Identify headings, numbers or notes mixed into lines and confirm the correct poem or sequence through section and opening words. A shelf title alone does not establish the poem’s full structure.

## Identify screen wrapping in long lines

Find the longest reference line and modestly change available font size or display width. A line that recombines was screen-wrapped, not necessarily authored as two lines. Record the complete original verse line before judging indentation or copying display breaks into a quotation.

## Do not infer authored lines from punctuation alone

Poetic lines may end without punctuation or contain several clauses. Compare against the reference rather than inferring lines from stops. Record merged authored lines separately from ordinary screen wraps, distinguishing content order from line presentation instead of issuing a vague layout complaint.

## Check stanza gaps as structure

Verify the last and first lines across a stanza boundary. Reflow may change blank height without losing text, but stanza identity still needs an intelligible cue. Do not demand pixel-identical spacing across devices or equate a smaller gap with missing content before checking sequence.

## Verify indentation against the reference

Distinguish intentional indentation or stepped layout from continuation-line indentation. If essential visual structure is lost, use the copy for limited text tasks and retain a reliable page reference for layout. Do not claim restored authorial formatting merely by inserting spaces into an unlabelled modified copy.

## Keep notes and translator commentary separate

Locate notes, introductions and translator commentary, verifying their role in context after search. Do not append commentary to verse because it shares a screen. Use available bookmarks or concise notes for boundaries, retaining the original edition as the structural reference.

## Preserve line order and provenance when quoting

For a short quotation, verify line order and identify title, author, translator and edition. Reflowed pages are not universal citations. Shorten an excerpt rather than arbitrarily relineating it to fit a card. A quote-card format does not itself validate layout or provenance.

## Retain a fixed-layout reference when needed

For visual poetry or page-dependent spacing, keep a reliable PDF or publication page separately labelled from the reading EPUB. Recheck conversions against the three anchors. Do not rename extensions or delete originals hoping for automatic repair; retain original, reading copy and notes with clear roles.

## Finish with two display widths

Check the three anchors at two available widths, separating stable structure from display wrapping. One device may suffice. Record a task-specific conclusion and do not generalise one poem’s success to every poem. Sample a structurally complex piece in future collections rather than only the first page.
