          <dc:description>In error-correcting codes, locality refers to several different ways of quantifying how easily a small amount of information can be recovered from encoded data.  In this work, we study a notion of locality called the s-Disjoint-Repair-Group Property (s-DRGP).  This notion can interpolate between two very different settings in coding theory: that of Locally Correctable Codes (LCCs) when s is large - a very strong guarantee - and Locally Recoverable Codes (LRCs) when s is small - a relatively weaker guarantee.  This motivates the study of the s-DRGP for intermediate s, which is the focus of our paper.  We construct codes in this parameter regime which have a higher rate than previously known codes.  Our construction is based on a novel variant of the lifted codes of Guo, Kopparty and Sudan.  Beyond the results on the s-DRGP, we hope that our construction is of independent interest, and will find uses elsewhere.</dc:description>
