During the weekend of Dec. 27 and 28, the Harvard University Library Office for Information Systems (OIS) will implement a software upgrade for HOLLIS, Harvard’s online integrated library system. On those days, the online HOLLIS catalog will be either limited in function or unavailable. The upgrade schedule is as follows:
On Saturday morning, Dec. 27, from 3 to 6:30 a.m., the HOLLIS Catalog will be unavailable.
On Saturday, Dec. 27, from 6:30 a.m. until Sunday, Dec. 28, 11 a.m., the HOLLIS Catalog will become available in “search only” mode. Users will be unable to log in to personal accounts to view or modify any personal account information. In addition, users will be unable to request holds or renewals.
On Sunday, Dec. 28, from 11 a.m. until 7 p.m., the HOLLIS Catalog will be unavailable.
The upgrade will be complete on Sunday, Dec. 28, at 7 p.m., when the HOLLIS Catalog will return to full operation. The HOLLIS upgrade will not affect library hours, nor will it limit the availability of the Harvard Libraries Web site; the Baker, Dumbarton Oaks, Harvard – Massachusetts Institute of Technology Data Center, and Biblioteca Berenson online catalogs; or the VIA (Visual Information Access), OASIS (Online Archival Search Information System), or Harvard Geospatial Library systems.
The software upgrade will affect only the administrative aspects of the HOLLIS system and not the public aspects of the catalog, which will remain essentially unchanged. According to Tracey Robinson, head of OIS, “This is a planned upgrade that we expect to happen completely as a matter of course. By scheduling it on Dec. 27 and 28 – when use of the online catalog is historically at a minimum – we have tried to ensure that Harvard users experience as little disruption as possible.”
