 The main challenges are:
 
-* currently 1.8B references documents (~800GB raw textual data); possibly going up to 2-4B (1-2TB raw textual data)
-* currently a single machine setup (16 cores, 16T disk; note: we compress with [zstd](https://github.com/facebook/zstd), which gives us about 5x the space)
+* currently 2.5B references documents (~1TB raw textual data); possibly going up to 2-4B (1-2TB raw textual data)
+* currently a single machine setup (16 cores, 16T disk; note: we compress with
+  [zstd](https://github.com/facebook/zstd), which gives us about 5x space, 2x
+  speedup)
 * partial metadata (requiring separate code paths)
-* data quality issues (e.g. need extra care to extract URLs, DOI, ISBN, etc. since about 800M metadata docs come from ML based [PDF metadata extraction](https://grobid.readthedocs.io))
+* data quality issues (e.g. need extra care to extract URLs, DOI, ISBN, etc.
+  since a good chunk of the metadata comes from ML based [PDF metadata
+  extraction](https://grobid.readthedocs.io))
 * fuzzy matching and verification at scale (e.g. verifying 1M clustered documents per minute)
 
 
 Internet Archive use cases for the output citation graph include:
 
-* discovery tool, e.g. "cited by ..." link for scholar.archive.org
-* lookup things citing this page/book/website/...
-* metadata discovery; e.g. identify popularly cited works which are missing (aka, have no "matched" record in the catalog)
-* Turn All References Blue (TARB)
+* discovery tool, e.g. "cited by ..." link on [fatcat.wiki](https://fatcat.wiki/release/bza3ovudezahlexibdtoytgtb4/refs-in)
+* lookup things cited by a [wikipedia page](https://fatcat.wiki/wikipedia/en:Internet/refs-out), papers citing [books](https://fatcat.wiki/openlibrary/OL2141999W/refs-in) or papers referencing web pages (wip)
