After Dave’s most recent post on keyword searches, a short discussion followed noting the (currently) UK-only ECCO, via JISC, supports conceptual word searches while the US ECCO only supports keyword searches. To be honest, I was unaware the US had not upgraded to the JISC version and was asked (since I’m a student at the University of London) to post some screenshots of the differences and perhaps write a post on it.
I am fortunate enough to have both access to the JISC Beta and the older version of ECCO–my individual school (Royal Holloway) provides JISC while the Uni. of London Library, Senate House, has the version with which most of you are familiar. There are several key differences between the two that result in completely different search results, as you will see throughout this post. NB: I’ll be providing a lot of screenshots here, so I’ve placed them after the jump.
