Paris : les boulevards / illustrations by Charles Franch ; text by Pamela Golbin. (OCLC #884298094)

Many books include on the title page verso a printer’s key which looks like a line of numbers:

    9 8 7 6 5 4 3

The smallest number present in the key indicates the print run of the volume you have in hand, so the key above would indicate the third print run for this edition. For each subsequent run, they remove the smallest number from the key.

This title’s printer’s key also includes years:

    2015 2016 2017 2018 2019 / 10 9 8 7 6 5 4 3 2 1

This volume was printed in 2015 and was the first printing, so for future printings they will also remove years as necessary, so the lowest one can indicate the printing year.

Date of Manufacture (RDA 2.10.6) is not a core element in RDA, and LC-PCC PS only considers it core for rare materials, so we typically do not record it in records.
