Online resource (datasets) "This dataset of 1,000 PowerPoint files was generated from indexes of the Web archives, which were used to derive a random list of 1,000 items identified as PowerPoint files and hosted on .gov domains. The set includes 1,000 unique files and minimal metadata about these, including links to their locations within the Library's web archive."-- Web archive datasets website. "Dataset originally created 11/6/2018."--README file "This dataset is based on exploratory work begun by the Library of Congress's Web Archiving Team in 2018. The goal of the work is to explore the contents of the Library's web archives through analysis of the indexes containing metadata from the harvested web content, as stored in CDX files. The metadata contained in the indexes was used for initial analysis, rather than the archived content stored in WARC and ARC container files, since W/ARC files present significant challenges due to large size and high processing requirements. The CDX indexes used in this initial analysis were six terabytes (TB) in size, which is a fraction of the web archive content in W/ARC files constituting nearly 1.5 petabytes (PB) at the time of analysis (November 2018)."-- README file Title from Web Archive Datasets website, viewed February 23, 2021. n-us--- Electronic government information United States Presentation graphics software United States Web archives United States JF1525.A8 s-Online Electronic Resource https://labs.loc.gov/work/experiments/webarchive-datasets/ https://hdl.loc.gov/loc.gdc/gdcdatasets.2020445282 2020445282 https://labs.loc.gov/work/experiments/webarchive-datasets/ rda DLC 210223 20250607104631.5 21913284 Converted from MARCXML to MODS version 3.8 using MARC21slim2MODS3-8_XSLT1-0.xsl (Revision 1.172 20230208) eng
