Missing Categories

Hello, I've also been doing this challenge on and off for a few years (574 more books to go!) and I have a few categories that I couldn't find a title for. The last post helped fill in two of them, but looking for books for these numbers:

000 - Computer Science, Information, and General Works
037 - Encyclopedias in Slavic Languages
038 - Encyclopedias in Scandinavian Languages
055 - Serials in Italian, Romanian, and Related Languages
058 - Serials in Scandinavian Languages
063 - Organizations in Central Europe; in Germany
066 - In Iberian Peninsula and Adjacent Islands
105 - Serial Publications
318 - General Statistics of South America
405 - Serial Publications
406 - Organizations and Management
452 - Italian Etymology
605 - Serial Publications
705 - Serial Publications of Fine and Decorative Arts
800 - Literature and Rhetoric
866 - Spanish Letters
867 - Spanish Humor and Satire
890 - Literatures of Other Languages
905 - Serial Publications

If I HAVE to read dictionaries and the like, I CAN, but I'd rather not if there are other alternatives.

Thanks!

000 - Computer Science, Information, and General Works
I have Henry Ruoff's The Volume Library in this slot. A general work on general information

--I am also missing something for 035. Do you have something here?

037 - Encyclopedias in Slavic Languages
There are various volumes of The Great Soviet Encyclopedia out there translated into English. Not fun, but they do the trick.

038 - Encyclopedias in Scandinavian Languages
Your guess is as good as mine. :)

055 - Serials in Italian, Romanian, and Related Languages
I've found no English language books that work here so far.

058 - Serials in Scandinavian Languages
Same here.

063 - Organizations in Central Europe; in Germany
Same here.

066 - In Iberian Peninsula and Adjacent Islands
You guessed it -- no English language books yet.

105 - Serial Publications
I have The Freud-Binswanger Correspondence here, but I think the classification is dubious

318 - General Statistics of South America
Brazil: A Handbook of Historical Statistics will be unfun, but it works.

405 - Serial Publications
Nothing here.

406 - Organizations and Management
Nada

452 - Italian Etymology
My list has Historical Syntax of the Atonic Personal Pronouns in Italian as an upcoming read, but I need confirmation from an actual library that has it in this section.

--I am also missing something for 458, 463, and 473. Trying for an actual book and not a dictionary.

605 - Serial Publications
Any issue of Make magazine will fit here.

705 - Serial Publications of Fine and Decorative Arts
I bought a copy of The &-Files Foss for the future.

800 - Literature and Rhetoric
I have Richard Lederer's Literary Trivia

866 - Spanish Letters
The Selected Letters of Federico Garcia Lorca works here.

867 - Spanish Humor and Satire
Mockery in Spanish Golden Age Literature

890 - Literatures of Other Languages
Signing the Body Poetic

905 - Serial Publications
Nothing yet.

I hope all that helps.

Thank you for the leads! I will look into those suggestions for sure!

For 035: I found "Institute of the Italian Encyclopedia: Founded by Giovanni Treccani" in the UIUC library catalog. I think I found it there because UIUC has books in Dewey and I was trying to find titles for categories that I didn't have anything in. I haven't looked into it any further than that.

Yeah, I do think some of these will just straight up be dictionaries and encyclopedias. Which, not fun, but that's why it's a challenge, I guess!
