    <subfield code="a">&lt;p&gt;A smaller-resolution (and therefore more portable) version of the Stable Random Projection Hathi Trust features described in my forthcoming article. The Northeastern repository is many individual files with 1280 random dimensions; this is just 640 random dimensions. The numbers are also experimentally encoded as half-precision floats, which cuts the file size by half at the cost of only being supported by my Python module. The net result is a file 1/4 the size of the full resolution ones for the paper that has, probably, something like 60-80% of the information content.&lt;/p&gt;

&lt;p&gt;The full file is &amp;#39;&lt;a href="https://www.zenodo.org/api/files/6d615dbd-65de-4391-93ac-91b302bb57e4/ht-640d-complete-half-precision.bin?versionId=0e9f5551-0888-454c-8bb8-0dd3f3d6d949"&gt;ht-640d-complete-half-precision.bin&lt;/a&gt;&amp;#39;. You can also download 11 smaller files organized by language.&lt;/p&gt;
