Nico WagnerJust released version 0.1.0 (pre-alpha) of polars-marc21 — a polars io plugin for reading MARC21 files. It is based on the MARC21 parser and the query engine from marc21-rs.
I would appreciate any feedback, new ideas, or reports of errors.
Ben Companjen 🟥@MishaVelthuis oh hey, it turns out that #code4lib can play this game! Are you keeping track of scores automatically, Misha?
I just released version 0.3.0 of marc21-rs. This version includes five new commands: describe, dedup, partition, frequency, and—most importantly—select.
I would appreciate any feedback, new ideas, or reports of errors.
For more information, see the documentation: https://deutsche-nationalbibliothek.github.io/marc21-rs/index.html
Oh, and I talked to another active user of https://code4lib.social in-person today! 🤩
My mind is still buzzing from #IIIF...

I'm running updates on the servers, #code4lib, so you may experience a few hickups.
OldInsuranceMapsLast month I presented at #Code4Lib: www.youtube.com/live/6nBJ… While preparing the slides, 10 minutes was feeling really short (especially for a new audience) but I reworked some things and I think it’s actually the best introductory talk about the project I’ve given!
