Hi Everybody,
I have been trying to purchase a copy of the USMLE COMPENDIUM produced by Dr.Guzman and published by INVISCO.com.
What it is is a type of database containing USMLE Step 1 syllabus arranged alphabetically.
It first came out in late 2008 but the link to purchasing this product does not seem to work any longer.

Any help would be much appreciated.
