Thanks Karen, Rene also mentioned the BASE (thanks). They only go as far as the third level of the DDC and in all the cases I checked, the DDC classes were assigned automatically. Meanwhile, I have found out that some university libraries have assigned subject metadata to the technical reports and articles archived in their institutional repositories, e.g., see: http://www.worldcat.org/title/supporting-oo-design-heuristics/oclc/19148 1189&referer=brief_results None of them have all the DDC, LCC, and LCSH metadata assigned, but it is a good start anyway. Some of them like 1400 research papers from the Carnegie Mellon University-School of Computer Science have proper LCSHs assigned but have been assigned the same DDC and LCC (i.e., LCC: QA76.C37 DDC: 510.7808), which I suppose is understandable considering the amount of work required for their proper manual classification.

I have found such a source here: http://www.base-search.net/Browse/Home No idea if it meets your needs, but it reminded me. kc -- Karen Coyle [log in to unmask] http://kcoyle.net ph: 1-510-540-7596 m: 1-510-435-8234 skype: kcoylenet ----- No virus found in this message.
