To remain functional, metadata schemas changes in response to shifts in information user needs and standards of information representation. This poster presents results of the longitudinal quantitative analysis of change occurring in a select group of library metadata records over time. This study traces the evolution of a sample of OCLC WorldCat metadata records created in MARC format according to new RDA standard of information representation. The same records were obtained at four data collection points at approximately one year intervals. Findings reveal a significant increase in the number of instances of a variety of metadata elements: both those introduced by the RDA standard and traditional pre\u2010RDA elements. This study, along with related research, contributes to the understanding of metadata change and its relation to improvements in metadata quality and information access.<\/jats:p>","DOI":"10.1002\/pra2.2016.14505301125","type":"journal-article","created":{"date-parts":[[2016,12,27]],"date-time":"2016-12-27T06:08:13Z","timestamp":1482818893000},"page":"1-5","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Quality over time: A longitudinal quantitative analysis of metadata change in RDA\u2010based MARC bibliographic records representing video resources"],"prefix":"10.1002","volume":"53","author":[{"given":"Oksana L.","family":"Zavalina","sequence":"first","affiliation":[{"name":"University of North Texas 1155 Union Circle #311068 Denton TX 76203"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vyacheslav","family":"Zavalin","sequence":"additional","affiliation":[{"name":"University of North Texas 1155 Union Circle #311068 Denton TX 76203"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shawne D.","family":"Miksa","sequence":"additional","affiliation":[{"name":"University of North Texas 1155 Union Circle #311068 Denton TX 76203"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2016,12,27]]},"reference":[{"key":"e_1_2_5_2_1","volume-title":"GSLIS Occasional Papers","author":"Bade D.","year":"2002"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1080\/01639370802183081"},{"issue":"3","key":"e_1_2_5_4_1","article-title":"Metadata and data quality problems in the digital library","volume":"6","author":"Beall J.","year":"2005","journal-title":"Journal of Digital Information"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.5860\/lrts.48n2.92-101"},{"key":"e_1_2_5_6_1","first-page":"238","volume-title":"Metadata in Practice","author":"Bruce T.R.","year":"2004"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1080\/14649055.1999.10765621"},{"key":"e_1_2_5_8_1","volume-title":"Cataloging quality, LC priorities, and models of the library's future","author":"Mann T.","year":"1991"},{"key":"e_1_2_5_9_1","volume-title":"FAST (Faceted Application of Subject Terminology) users: Summary and case studies","author":"Mixter J.","year":"2013"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.1108\/S0065-2830(1993)0000017007"},{"key":"e_1_2_5_11_1","unstructured":"OCLC.
