Answer

Yes. For example, QC981. 8. C5 G38 2008 should be typed in exactly so: QC981.8.C5 G38 2008 (i.e., space b/n 5 and G, and b/n 8 and 2, only). Capitalization of letters doesn't matter. And, because call numbers are generally unique, you can usually find the right record in one shot by searching it anywhere in the record.You must use spaces in between a number and a letter where a dot is lacking, but no spaces in between dots and letters or dots and numbers.
