Book Isle filenames and display titles: keep a route back to originals

Personal ebook collections often have three different names: disk filename, internal title and Book Isle display title. They may come from separate sources. Use about ten samples to map these identities for later migration, replacement and editing rather than renaming the whole collection immediately.

Understand the three naming roles

Filenames locate originals on disk and servers; internal metadata can hold author, title and series; shelf display data supports reading. They need not rewrite one another automatically. Record all three for a sample and compare its title page before assuming the longest name is the correct formal title.

Collector remarks and scan dates may be unsuitable display titles but useful source clues. Keep them externally rather than erasing them. Mark conflicting information for review and use copyright, author and edition evidence instead of guessing from cover design.

Choose only necessary filename fields

Prefer a recognisable title, author or translator and edition distinctions, retaining the genuine extension. Add consistent volume numbering for series. Every file need not carry every field; similar books should remain distinct and understandable later without stuffing topic labels and reviews into their names.

Try the rule on copies and inspect sorting. Servers or other software may depend on paths, particularly Calibre-managed directories that should not be rearranged casually. Editing shelf display names does not require moving originals at the same time; organise the two layers separately first.

Edit only verified shelf metadata

Update title, author and series against text and inventory, save and inspect the list. Handle one book at a time and reopen it to confirm you selected the right entry. Similar covers and abbreviations can mislead; use list view where useful and avoid applying identical data to different translations in bulk.

Keep short edition distinctions where needed. Do not replace reading status with finished in a formal title or use the author field for subjects. Clear field roles make later searches and filters understandable and help verify data on another device.

Map shelf entries back to files

Keep a lightweight external table of display title, original filename, location, edition and primary reading format. For companion formats, distinguish the everyday copy from source or layout reference. A note export containing only a title can then be traced to an actual edition.

The content inventory does not need passwords. Update source locations after remote moves while retaining filenames and editions as clues. Save dated copies in a place you manage. This is not a database backup, but it helps retrieve and reimport files reliably.

Check what search is matching

Search the new display title, author and known text separately, observing metadata versus text matches. An old filename abbreviation may no longer be the most useful query. If no result appears, clear other filters and inspect scope before changing metadata again.

Do not stuff every source remark into a title just to make all words match. Use author, series and subject labels appropriately, with the external map for filenames. Full-text search depends on extractable text; image scans may not enter it, regardless of how clearly they are named.

Compare before reimporting or remote updates

When a similar book appears from another source, compare edition, contents and quotations before handling duplicates. Different names can represent the same text and identical names different revisions. Names and similar sizes alone are weak evidence for deletion; compare actual passages.

After external renaming or moving, a remote listing may need browsing or updating. Confirm the new file opens, then inspect shelf access before declaring the text damaged. Retain important notes first rather than deleting an old record merely to establish its new source.

Verify by finding the original

Choose three organised books, start with their shelf titles and use the inventory to locate original files. Check author, edition and a passage. This round trip demonstrates a useful naming system; if you still guess folders from memory, add missing information instead of redesigning every name.

Record the rule for future additions and which old books remain unchecked. Small batches allow rollback and reveal genuine edition differences. The goal is readable content, retrievable files and clear sources, beyond uniform-looking covers and names.
