Two new domains to keep a tab on:

- https://r7rsindex.com/ announced at https://www.reddit.com/r/scheme/comments/snygyj/r7rs_procedure_index_site_for_searching_standard/ source at https://github.com/arvyy/r7rs-index-site

And the fruit of my own deed:

- https://scheme.rs/ also there is https://scheme.rs/comparator/ that is not linked from the index, source at https://git.sr.ht/~amirouche/scheme.rs
