+title: arXMLiv 2020 - An HTML5 dataset for arXiv.org
+---
+
+### Release
+ - This page documents: arxmliv 2020 (latest)
+
+### Contents
+ - 1,581,037 HTML5 documents
+ - 354 ZIP archives, in arXiv's Year-Month `yymm` naming scheme.
+ - e.g. `2012` stands for December 2020, and **not** for the year 2012.
+ - The HTML sources total `236 GB` packaged, and `2.1 TB` unpacked.
+ - you also need 1.6 million free inodes to unpack the full data (check via `df -ih .`)
+
+### Download
+ - [Download link](https://gl.kwarc.info/SIGMathLing/dataset-arxmliv-2020)
+ - [SIGMathLing members](/member/) only. Joining is free and mostly a legal checkmark on our end - all researchers welcome!
+
+### Description
+
+This is the fourth public release of the arXMLiv dataset generated by the [KWARC](https://kwarc.info/) research group.
+It contains HTML5+MathML conversions of the scientific documents from the arXiv.org preprint server, upto and including the end of 2020. It offers a 15% increase in available articles over our 08.2019 release.
+
+The release also provides the associated conversion metadata under `meta/grouped_by_severity.zip`. The severity information allows to filter by whether the latexml process completed cleanly, with warnings or with recoverable errors.
+
+A unique feature of the arXMLiv generation process is latexml's cross-referenced and lexematized MathML representation for math syntax. Scroll to the bottom of the page for an example snippet.
+
+This version of the dataset has had minimal manual quality control, and we offer no additional warranty beyond the latexml severity reported.
