Q. Where can I find the architectural plans for the Beinecke Rare Books and Manuscripts Library?

Regretfully, the Beinecke Library does not have scans of its architectural plans available online. The originals are held by another archival repository, the Manuscripts and Archives Department of Yale University. To ask them about the possibility of getting copies of these, please contact them at: mssa.assist@yale.edu

 In the meantime, there are several plans published online here:

There is a series of construction photographs here:
