HathiTrust makes ingests reports [1] available for institutions that are contributing content. Below is a description of the information in the reports.
| No digital object | Items that have bibliographic data in HathiTrust, but have not been queued for ingest, ingested, or failed ingest |
| Not in GRIN | Items that have bibliographic data in HathiTrust, but do not exist in GRIN (subset of "No digital object") |
| No bib data | Items that are available on GRIN and not high error or surrogate (i.e., "ingestible"), but have not had bib data loaded into HathiTrust |
| Queued/in process | Items that have entered the queue to be ingested. The typical ingest rate is up to 30,000 volumes per day; items are ingested in the order enqueued. |
| Delayed in process | Items that are queued for ingest but have not had action in at least 5 days. Normally this indicates items are delayed "IN PROCESS" at Google. |
| NAFD | Items in GRIN (with or without bibliographic data in HathiTrust) with status "NOT_AVAILABLE_FOR_DOWNLOAD" |
| CHECKED_IN | Items in GRIN (with or without bibliographic data in HathiTrust) with status "CHECKED_IN" |
| High error | Items in GRIN (with or without bibliographic data in HathiTrust) with greater than 15% overall error. These may be ingested if quality rises above the error threshold. |
| Surrogates | Items in GRIN (with or without bibliographic data in HathiTrust) with condition 31 and src_library_bibkey set. These are "Surrogate" items, returned when a physical copy of a volume from one library has already been scanned by Google from another. |
| Failing ingest | Items that have failed ingest in the last 7 days (subset of "Failed ingest"). Items in this category will not be automatically retried, but they will be examined and retried if the error was transient. |
| Failed ingest | Items we have attempted to ingest that have failed ingest for any reason (see Ingest Logs [2]) at any time. Items in this category will not be automatically retried, but they will be periodically reviewed & retried if conditions warrant. |
| Ingested in last week | Rough count of items ingested in the preceding week (count from previous week's ingest log [2]) |
