Five new contributors included in June ArchiveGrid index update

We at OCLC Research are pleased with the new additions to ArchiveGrid after our most recent index update, which took place on Saturday, June 9. Along with five new contributors in the United States, Canada, and United Kingdom, our index size increased by 6,032 collection descriptions. Here is how that number breaks down: 4,953 of those descriptions are MARC records from WorldCat, and 656 EAD files and 423 HTML files were harvested from contributors.

How those numbers compare with our February 2011 index report is shown in the graph below. Two things account for the growth of MARC records (blue): Work we have done to identify and include additional WorldCat data contributors, and the general on-going growth of WorldCat. Dips in MARC records happened after we improved our selection algorithms to identify archival collection descriptions.

On a deeper level, these numbers represent a greater wealth of historical content for people to discover in ArchiveGrid. Our inclusion now of 237 MARC records from Lincoln Memorial University tells people what’s inside each collection about Abraham Lincoln and the Civil War at LMU’s prestigious Abraham Lincoln Library and Museum. Also, 357 finding aids for moving image archival collections from Northeast Historic Film are now getting greater exposure on the web after we harvested their finding aids directly from their website.

We would also like to welcome and show appreciation for our other three new contributors:

California State University, East Bay

University of Calgary

University of Essex, Colchester Campus

As all of our contributors continue to put more collection descriptions online, we look forward to seeing those higher numbers represented in ArchiveGrid after each of our monthly and bi-monthly index updates.
