For anyone not familiar with it, the rdabf tag refers to the
RDA Bibliographic Format registry (rdabf: <a href="https://www.rdaregistry.info/termList/bookFormat/">https://www.rdaregistry.info/termList/bookFormat/</a>)
<br></div><div><br></div><div>Unfortunately, in many cases these are books from the machine-made era.
Here is an example from 1863: OCLC 14985739. The definition of 8vo in the Registry is, as it should be:
"A bibliographic format consisting of one or more leaves that are 1/8 of the whole sheet," and of course, the size of the original sheet is very difficult to ascertain in a book produced in 1863 on machine-made paper.</div><div><br></div><div>The records I have found so far are lacking a 300 $$c subfield. They also were originally entered into OCLC decades ago, but were recently updated. My guess is somebody decided to strip 8vo from the end of 300 and move it to an rda field. Unfortunately, they failed to consider that many older records used 8vo as a general indicator of size, and not as "Bibliographic Format" as defined in the registry, so we end up with records with missing and erroneous information.</div><div><br></div><div>I'll be fixing this one soon, but I wonder how many there are.</div><div><br></div><div>Bob Steele</div><div>Cataloging Librarian</div><div>Jacob Burns Law Library</div><div>George Washington University<br>
