The Libraries will be performing a system upgrade on the Barton catalog this coming weekend. From Friday, March 18 at 10pm until Monday, March 21 at noon, Barton will be accessible as usual through http://libraries.mit.edu/barton, but not from http://library.mit.edu.
Your Account features will be unavailable during the upgrade.
Interlibrary requesting through the Boston Library Consortium (BLC) will also be down, since that depends on communications with Barton. BLC holdings will be available for searching only at http://mit.worldcat.org , but requesting will be blocked.
We apologize for the inconvenience. Have questions? Ask Us!
