Online LC-Dewey conversion tool

Is there such an animal? All I've been able to find is a lot of references to the Greenwood publication, and I won't have enough items in my personal library to convert from Dewey to LC to make buying a copy, even a used one, economically practical.

There's a subscription-based one available from the Library of Congress called "Classification Web," but it's still $325 / year and it's just based on statistical mapping, so it's not always that accurate. (LC and Dewey are different enough beasts that you can't always get consistent mapping from one number to another.)

Am I right in thinking that you're trying to find Dewey numbers for the books in your library?

No, I've got the DDC numbers and am trying to convert them to LCC. And $325 for an annual subscription is even more financially preposterous, from my own POV, than buying a copy of Scott would be. (I estimate that I'll have fewer than a dozen numbers to convert by the time I'm through.)

Ah, I see. Well, I can help you out there, actually, because I've got access to the full LC schedules. Post the DDC numbers here or in another thread and I'll be happy to look them up for you. :)

The two that have me stuck at the moment are 378.005 and 373.76455.

Try LB2300 for the first one. The second one is proving a bit trickier. Is it about secondary education in Texas?

Actually, try LB1607.52.T4 for the second one.

Both of 'em are school annuals, and the second one is for a high school, so secondary education is a reasonable class for it. I'd worked out it had to fall under LB, but a full number eluded me.

I know this is an old post, but if another comes upon it I found this site online that may help.
It has both DDC to LCC and LCC to DDC charts.

Thank you for that -- although I went to use it, and because my title is an LC of DS797.77 apparently most of the D classifications are...still work in progress over there.
::sigh::

Also, depending on if searching individual titles is feasible or not, OCLC Classify is a useful tool:

I found this tool that might be of use: https://guide.unwsp.edu/dewey

Wondering if anyone is following this. I find the links and tools listed don't get me what I need for LOC numbers. I've run into the same problem as the OP and am looking for guidance/help.

Thanks in advance,

This seems to be a cross-walk from DDC to LCC: https://www.questionpoint.org/crs/html/help/en/ask/ask_map_ddctolcc.html

>13 lssc_libraries: If you use Amazon as your source, you will only get classifications if other people have them entered. (You also get Amazon data, which isn't that bad for new books, but can be really awful for older books.) If you use a library source you will get the classifications that library uses. I suggest starting with Overcat, because you will often get a choice of entries from library sources and can chose the one that best suits your needs. On the other hand, if you want LCC, it would make sense to use Library of Congress for your first choice of source.

You can also look books up in LoC from the work page and often get the LCC that way. Slaying Goliath is listed with LCC LB2806.36 .R385 2020
