Different kinds of publication, the same problem: the edition already exists but is locked inside a PDF. Here is what that means per type.
Fixed section labels, many sidebars and tables, articles running across the fold. That is exactly where recording the section labels once pays off: from then on they are always recognised and every article lands under the right heading.
Often a small editorial team and little time. The edition already exists; the point is getting it online without anyone spending an evening retyping. Members read it on the bookshelf, phone included.
Narrow columns, many short items, headlines spanning several columns. Column detection is tuned for this, so lines from adjacent columns are not glued together.
Lots of imagery, atmospheric layout, drop caps and pull quotes. Photos come across at source quality with the right caption attached.
Several titles under one roof. Each keeps its own rules while processing and billing come together in one place, with a monthly overview per title.
Back volumes that exist only as PDFs become searchable articles. A filing cabinet turns into an online source.
An edition that is online no longer costs editorial time but does earn you visibility: separate articles with real text can be found through search engines, where a PDF barely can.
And because you can export the articles as HTML and JSON, you stay free to use them in your own website, newsletter or app.
