December 4, 2007 - "21th" for 21st

The typo "21th" is a high probability error in online catalogs. Many of the 93 results in OhioLINK were for 18th century titles on microfilm--and it's hats off to those who verify title entries by checking microfilm reels! Luckily, many 18th century titles are now available electronically--a simple click is all that is needed to verify typos from the original piece. Conference heading, subject heading, and summary note typos with "21th" require some analysis. Should the typo be corrected to "20th" or "21st"?
