Are AH52264, AH66175 and AH70594 duplicates, arisen due to automated snapshotting of the same resource at different dates?

ah <- AnnotationHub()            # all
ucsc <- query(ah, 'UCSC')        # ucsc 
txdbs <- query(ucsc, 'TxDb')     # txdb 
txdbs

We rebuild the TxDb per release cycle to account for any changes; A new version but for the same genome build. The most recent will likely be what you want but we don't strictly replace so people could replicate older analysis.

Thank you Lori :-) .

Also note that this information is available, so you can check for yourself.

> z <- query(hub, c("UCSC","TxDb","mus musculus"))
> z
AnnotationHub with 5 records
# snapshotDate(): 2019-10-17 
# $dataprovider: UCSC
# $species: Mus musculus
# $rdataclass: TxDb
# additional mcols(): taxonomyid, genome, description,
#   coordinate_1_based, maintainer, rdatadateadded, preparerclass, tags,
#   rdatapath, sourceurl, sourcetype 
# retrieve records with, e.g., 'object[["AH52263"]]'

Thankyou James. Knowing it is policy (for backward compatibility) rather than artifact helps to appreciate the redundancy :-)
