Or take both in one feed
Yes - as description and delivery: the dump says what a book is, the corpora supply what the book says.
A working pattern: load the editions dump and resolve candidate titles to canonical keys using isbn_10/isbn_13 and lc_classifications, then attach running text by joining those Library-of-Congress hooks against LoC-PD-Books rows, which carry lccn directly. The result is a corpus whose every document keeps its bibliographic identity - author, publisher, classification, publication date - instead of raw text with a filename for provenance. Reception layers bolt on the same way, with ratings and reading-log rows keyed to work identifiers.
Two cautions from the records. First, the bridge is partial by construction: LoC-PD-Books holds only books the Library of Congress digitized, while the dump spans a global catalog, so expect matches on a minority of editions and fall back to title-author-year fuzzy matching for the rest. Second, the sides move differently - a monthly full snapshot against continuously committed repositories pinned per sha - so date-stamp each pull deliberately rather than assuming they describe the same moment.
Or take both in one feed: Datadory delivers them alongside the rest of the publishing catalog, normalized to their documented field dictionaries, delivered daily, weekly, or hourly - your call.

Fair questions
Is Open Library Monthly Data Dumps better than Hugging Face Datasets Hub - Books Search?
Better for different questions entirely. The dumps win when you need one authoritative bibliography: editions, works and authors as fixed-shape records carrying ISBNs, classifications and revision history, scoring 10/10. The Hub wins when you need text itself: roughly 770 corpora led by LoC-PD-Books at about 140,000 books and 8 billion OCR words, scoring 9/10. One describes books; the other hands them over.
Do Open Library Monthly Data Dumps and Hugging Face Datasets Hub - Books Search cover the same ground?
The subject, yes; the columns, almost never. That makes them complements rather than substitutes.
Which dataset is bigger, Open Library Monthly Data Dumps or Hugging Face Datasets Hub - Books Search?
Depends on the axis. By bytes, the dumps: about 12.4 GB compressed for all record types, 29.6 GB once every past revision rides along. By count of distinct collections, the Hub: roughly 770 separately curated corpora ranging from under 1K records to billions of words. One catalog dumped whole versus many catalogs behind one search.
Which should an NLP team sample first?
The Hub, almost always: LoC-PD-Books alone yields about 8 billion words of typed OCR text, and Parquet-style corpora load straight into training pipelines. The dump earns its place next, supplying the bibliographic identity - ISBNs, classifications, publication metadata - that turns a pile of texts into an attributable corpus. Sample both and pick by fit.
