This is an interesting project by the German cataloguer Bernhard Eversberg. He’s created a browsable database of LC subject headings. The starting point is from here <http://www.biblio.tu-bs.de/db/lcsh/index.htm>.
You can browse on: LCSH Terms; Phrases; Words; Names; and Titles.
Here’s an example using the term ‘remedies’ in the Phrase browse:
o remedies (12)
o remedies : Administrative remedies
o remedies : Equitable remedies
o remedies : Exhaustion of administrative remedies
o remedies : Exhaustion of local remedies [International law]
o remedies : Extraordinary remedies
o remedies : Extraordinary remedies [Roman law]
o remedies : Herbs — Therapeutic use
o remedies : Naturopathy
o remedies : Post-conviction remedies
o remedies : Provisional remedies
o remedies : Remedies [Islamic law]
o remedies : Remedies [Law]
o remedies : Traditional medicine
o remedies islamic law : Remedies [Islamic law]
o remedies law : Remedies [Law]
o remedies, administrative : Administrative remedies
o remedio : Virgen del Remedio [Alicante, Spain]
Clicking on a heading brings up the authority record in the right-hand side of the display along with the opportunity to try a search for the term in WorldCat and some other databases.
He also provides a Boolean interface here <http://www.biblio.tu-bs.de/db/lcsh/detail.php> where you can either search or browse the LC subject authority file.
Give it a try and see what you think.
