When EBSCO acquired NetLibrary from OCLC in March 2010, it obtained a fully formed ebook platform that already had a large collection of about 200,000 ebooks from 500 publishers available in 17,000 sites worldwide. The challenge was to smooth out this platform, now known as Ebooks on EBSCOhost, so that it could migrate to the EBSCO interface and there be remade.
