Import Markdown, HTML, RTF and DOCX as personal reading material, check text, external images and layout limits, then organise a searchable document shelf.

English translation of the [Chinese original](<https://allluckly.cn/guides/nasbook-document-reading/>), translated on 2026-10-23. The article body uses automated translation; app descriptions, historical reading notes and video subtitles receive separate editorial checks. Original publication dates, attribution, code and version notes are retained.

Beyond novels, Book Isle can read your own Markdown, HTML, RTF, and DOCX documents. When adding work materials, first check text completeness and suitability for continuous reading rather than expecting a replacement for the original layout software.

## Choose materials suited to the bookshelf

Prepare four small samples: a Markdown document with headings and a list, a fully saved HTML document, a piece of RTF text, and a DOCX with two chapters. Your own practice content is enough; do not test with the only copy of a formal contract or complex report. Keep each original and note the expected headings, paragraphs, and image count.

These documents may rely on external styles, online images, embedded fonts, or special objects. Book Isle primarily handles reading and management. Do not assume every table, footnote, comment, formula, and tracked change will appear exactly as in the original editor. If exact layout is essential, retain a PDF for comparison before deciding whether text-based reading is suitable.

## Import one format at a time

Choose one sample through the bookshelf's “Local File Import,” verify its format in the preview, and import it. Open it, check the title, then compare each paragraph with the original. Only move to the next format after confirming this one works. Importing forty files together makes it difficult to identify which structures cause display differences.

For example, a Markdown sample can contain a first-level heading, three list items, and a quotation. Check text order and paragraph boundaries while reading. Different styling from the editor may not impede understanding, but missing list items, changed order, or a code block flattened into one paragraph warrant checking the original before deciding whether to convert it. Do not delete the original document before checking.

## Check that HTML resources travel with the file

A common HTML problem is a saved main file whose images and styles still point to the internet or an adjacent resource directory. After importing, check the body, then temporarily disconnect networking and see whether images remain. If only text survives, resources may not have been fully packaged. This is not directly related to NAS download speed or bookshelf sorting.

A web link is not a local document. For long-term reading, save a complete copy lawfully and organize its relative paths with suitable tools, or create a standalone EPUB/PDF. Do not treat a logged-in page address as permanently available offline content; login state and web resources can change.

## Focus on content structure in DOCX and RTF

After opening DOCX or RTF, check paragraphs, headings, and text around tables in their original order. If charts are present, confirm that their explanations were not omitted. A reading copy suits consulting the main content, but formal editing, review, and layout delivery still belong in the original editor. A displayed bookshelf name is reading metadata, not proof that the document's internal title field was rewritten.

For course notes, simplify overly complex layouts into short headings, ordinary paragraphs, and clear numbering. One topic per section suits a phone better than many text boxes on a page. Use a corresponding PDF for exact formulas or multiple columns. This assigns formats by purpose; it does not require converting every document into one format.

## Organize a small reference bookshelf

Give the four samples clear titles such as “Photography Notes—Basic Concepts” and “Photography Notes—Equipment Checklist,” and add tags reflecting actual content. A format describes storage, while tags better express a subject. If the same material exists as DOCX and PDF, retain version dates to identify which copy was revised this week.

For the first organization pass, two tags such as “Study” and “Work Reference” are enough. Subdivide gradually after reading. Creating dozens of categories too early makes similar labels hard to choose between. Confirming that documents open and search correctly matters more than polished covers. Covers aid recognition but do not replace version and content checks.

## Search and position checks

Choose a distinctive sentence in one document. Once import and indexing preparation finish, search for it from the bookshelf. Start with a short term and check whether the result comes from the title or body. Text inside scanned images, embedded objects, or parts not parsed as text is not guaranteed to enter the full-text index. If nothing is found, inspect the actual reading page before assuming the index is damaged.

Read two or three paragraphs, exit, and reopen to check whether the position is reasonable. After external revisions and reimport, paragraph count and structure may change, making an old position inaccurate. Keep a short source quotation and document version in important notes to find the context in a new edition rather than relying only on a percentage.

## Common questions and format choices

**Why does an imported DOCX not look like Word?** Import and reading support do not mean complete document-editing or layout compatibility. Recheck text boxes, complex tables, footnotes, and revision information in the original editor. If pages must match exactly, export a PDF first and read it as fixed layout.

**Why are images blank in HTML?** Check whether images are on an external network, require login, or were saved alongside the main file. Renaming the HTML file alone cannot repair resource paths. For long-term reference, prioritize lawful copies that work independently.

**Must every Markdown symbol be removed?** Inspect the actual display first. There is usually no need to remove every markup symbol manually just to read. Only simplify a copy if the structure truly impedes understanding. Keeping the original helps with later editing and generation of other formats.

## Next steps

After organizing, continue with [Editing title, author, and series](<https://allluckly.cn/en/guides/nasbook-metadata-editing/>), or use [Full-text search](<https://allluckly.cn/en/guides/nasbook-full-text-search/>)to establish a habit of searching across documents. For materials that must retain page and formula positions, see [PDF navigation methods](<https://allluckly.cn/en/guides/nasbook-pdf-navigation-search/>).
