value of 'volumeCount' variable in CFR collection JSON output

[nirmalapudota]

Hi Team,

I am trying to construct the CFR-2018 section level index with the help of CFR collection API call. E.g., this API call (https://api.govinfo.gov/packages/CFR-2018-title12-vol1/summary?api_key=DEMO_KEY) provides ‘volume1’ header level information in CFR Title 12 as JSON output.
“{"title":"Banks and Banking","collectionCode":"CFR","collectionName":"Code of Federal Regulations (annual edition)","category":"Regulatory Information","dateIssued":"2018-01-01","detailsLink":"https://www.govinfo.gov/app/details/CFR-2018-title12-vol1","granulesLink":"https://api.govinfo.gov/packages/CFR-2018-title12-vol1/granules?offset=0&pageSize=100","packageId":"CFR-2018-title12-vol1","download":{"xmlLink":"https://api.govinfo.gov/packages/CFR-2018-title12-vol1/xml","pdfLink":"https://api.govinfo.gov/packages/CFR-2018-title12-vol1/pdf","txtLink":"https://api.govinfo.gov/packages/CFR-2018-title12-vol1/htm","modsLink":"https://api.govinfo.gov/packages/CFR-2018-title12-vol1/mods","premisLink":"https://api.govinfo.gov/packages/CFR-2018-title12-vol1/premis","zipLink":"https://api.govinfo.gov/packages/CFR-2018-title12-vol1/zip"},"branch":"executive","pages":"1118","governmentAuthor1":"National Archives and Records Administration","governmentAuthor2":"Office of the Federal Register","suDocClassNumber":"AE 2.106/3:12/","documentType":"CFR","titleNumber":"12","partRange":{"from":"1","to":"199"},"volumeCount":"8","publisher":"Office of the Federal Register, National Archives and Records Administration","otherIdentifier":{"migrated-doc-id":"12CFR"},"lastModified":"2018-08-03T21:54:07Z"}”

I thought the {"volumeCount":"8"} indicates the total number of volumes in CFR Title 12. But it seems not, there are total 10 volumes in Title12, here is the API link to get Volume10: https://api.govinfo.gov/packages/CFR-2018-title12-vol10/summary?api_key=DEMO_KEY.

Could you confirm what indicates the “volumeCount” key in the JSON output?

Thank you

@nirmalapudota -

volumeCount is intended to indicate the number of volumes within a given title of the CFR for that particular year.

That metadata is derived from information in the text of the document. In this case, the volume 1 text indicates that there are eight volumes.

[[Page ix]]

                          THIS TITLE

Title 12--Banks and Banking is composed of eight volumes. The parts
in these volumes are arranged in the following order: Parts 1-199, 200-
219, 220-229, 230-299, 300-499, 500-599, part 600-899, and 900-end. The
first volume containing parts 1-199 is comprised of chapter I--
Comptroller of the Currency, Department of the Treasury. The second,
third and fourth volumes containing parts 200-299 are comprised of...

whereas the text from title 10 indicates that there are ten.

[[Page ix]]

                          THIS TITLE

Title 12--Banks and Banking is composed of ten volumes. The parts in
these volumes are arranged in the following order: Parts 1-199, 200-219,
220-229, 230-299, 300-499, 500-599, 600-899, 900-1025, 1026-1099, and
1100-end. The contents of these volumes represent all current
regulations codified under this title of the CFR as of January 1, 2018.

It appears that in the publishing process, a decision was made to further split the title into multiple volumes (i.e. from 900-end to 900-1025, 1026-1099, and 1100-end)

got it. thank you. In order to get the correct volume count and corresponding part ranges, seems it is a good idea to construct the summary api links by increment on 'vol' string in '/CFR-2018-title12-vol10/' (https://api.govinfo.gov/packages/CFR-2018-title12-vol10/summary?api_key=DEMO_KEY.).

Thanks
