I have a map that includes the scale as a representative fraction and with a decimal(see attached photo) as 1/41436,6. This is an 1891 Russian government nautical chart.

I calculated the scale and the 414,363 is approximately correct.

The MARC record will not allow me to list the scale in the 034 as 414363.6.

Possible options as I see it:

Option 1

034  414363

255 Scale 1:414,363.6

Option 2

034 414364

255 Scale approximately 1:414,364.

500 "Masshtabʺ 1/414363,6 ... ."

How would you catalogers handle this?

Thanks.

Angie
